Client

ADManager Plus can be accessed from a web browser by entering the IP address or computer name and
port number of the server as the URL.

Eg: admp-client:<portnumber> (or) 193.45.23.4:<portnumber>

It can also be accessed from a mobile device using the ADManager Plus Android or iOS application. You
can log in to ADManager Plus using ADManager Plus authentication, domain credentials, single sign-on
(SSO), smart card authentication, and more.

Server

You can deploy ADManager Plus in any Windows machine in your domain. Once the product is installed,
it automatically discovers the AD domains in your network. You can also manually configure new domains.

Database

By default, ADManager Plus comes bundled with a PostgreSQL database, but can also be migrated to an
external MS SQL database. On the first of every month, the database is backed up automatically to avoid
data loss due to untoward incidents. All management and reporting actions performed using ADManager
Plus is recorded as audit reports and are stored in the product's database. By default, these audit reports
are archived and you can customize the storage location and retention period for these audit reports.

ADManager Plus' technology stack:

Client-side of the application is developed using HTML, CSS, JavaScript, jQuery plugin, Ember framework,
and Jakarta Server Pages (JSP, formerly JavaServer Pages).

Server-side framework is developed using Java, Native C, and C#.

ADManager Plus uses Java Database Connectivity (JDBC) to connect to databases.

ADManager Plus allows web browsers and servers to communicate using the HTTP/HTTPS and LDAP protocol.

2. ADManager Plus login process

The technician or administrator must log in to the application to perform management actions, generate
reports, and delegate tasks.

ADManager comes with three built-in technician accounts:

Admin
Help desk
HR Associate

Apart from these, you can configure any number of AD user accounts as technicians. Except the default
admin role, the other roles can be modified or removed. Using ADManager Plus, you can delegate the help
desk roles to users and groups. Delegating a role to a group would result in all the group members having
permission to perform the tasks defined in that role. Technicians can be delegated roles in the tool without
elevating their rights in the AD.

When technicians enter their username and password, the tool:

1. Performs AD authentication for the help desk technicians configured in the product and database
authentication for the built-in technicians.
2. Validates account details with respect to ADManager Plus configuration for technicians.
3. Performs authorization.

2.1 Authentication

Users can log in to ADManager Plus using domain authentication, Two-Factor Authentication (2FA), and
SSO authentication services.

During domain authentication, ADManager Plus will perform LDAP* binding with the configured DC using
ADsOpenObject API. It will then validate the password with the domain controller and check if the given
account is expired, locked-out, or disabled in AD, or if its password has expired. If any of the above cases
are true, the binding will fail and the tool will not allow the user to log in.

2FA

ADManager Plus offers 2FA through authentication services such as Duo Security, Google Authenticator,
SMS verification, Microsoft Authenticator, RSA SecurID, and One Time Password (OTP) via email. When a
user tries to log in to ADManager Plus, they are first authenticated using their username and password. If
it is successful, they are directed to the configured authentication service (Duo, Microsoft Authenticator,
SecurID, or RSA) or asked to enter an additional piece of authentication information such as OTP. If the
second step is also successful, the user is allowed to log in to ADManager Plus

Duo Security: Once the user enters the credentials, the tool authenticates it with AD. On successful
authentication, username and application key will be sent to Duo Security for verification. Upon successful
verification, the user will be logged into to ADManager Plus. The Duo Security secret key is stored in the
database using AES-CBC encryption with PKCS5 padding.

RSA SecurID: For RSA authentication, ADManager Plus does not store any key information, as the
configuration file (sdconf.rec within AMConfig.zip) received from RSA server stores the configuration
details. Users can use the security codes generated by the RSA SecurID mobile app, hardware tokens, or
tokens received in their mail or mobile to log in to ADManager Plus.

SSO

You can set up SSO to access ADManager Plus through NTLM or SAML authentication.

2.2 ADManager Plus technician validation

When a user account is configured as a technician, information such as technician name, AD account
status, roles, licenses, and privileges is stored in the product database. Once AD authentication succeeds,
the user account information will be validated with this configuration. If there is no configuration**
available, users will not be allowed to log in.

2.3. Authorization
In this step, the tool will fetch the delegated roles and domains from configuration details stored in the
database and assign them to the technician, and a session will be created for the technician in the
browser.

*Only for AD users. The built-in technicians will be authenticated using the database. LDAPS can be
configured in connection settings of ADManager Plus.
**For group-based delegation, user configuration happens during the login process.

3. ADManager Plus modules

3.1 AD management

When an AD management action is initiated, ADManager Plus will use an LDAP query to identify the
desired AD objects, perform the necessary action in AD using Windows APIs, and store the resulting data
in the database. It will then retrieve the data from the database and display it on the console.

3.2 AD reporting

ADManager Plus report library contains more than 200 out-of-the-box reports that provide information
on users' real last logon times, inactive AD users, group members (including nested group members),
NTFS permissions, and more. These reports can be exported in PDF, Excel (XLSX), CSV, CSVDE and
HTML formats.

When a user initiates a report generation action, the web client will send the input to the server via
HTTP/HTTPS. Based on this input, the server will construct an LDAP query. The LDAP query is executed
in AD, and the results will be stored in database and displayed on the ADManager Plus console. The tool
uses IDirectorySearch (API) for retrieving reports.

APIs used:
IDirectorySearch::ExecuteSearch
IDirectorySearch::GetColumn

3.3 ADManager Plus delegation

Roles in ADManager Plus:

ADManager Plus offers predefined help desk roles that can be assigned to help desk technicians. These
roles can be deleted or modified based on your needs. However, the Super Admin role, which contains all
the privileges, cannot be deleted or modified. You can also create customized roles and assign them to the
desired users to empower them to perform AD tasks within the specified administrative boundaries. Every
time a role is created, the tool creates a Role ID and every management or reporting action that is defined
in the role is assigned an ActionID. The Role IDs and ActionIDs are stored in the product's back end
database. Every role that has been created, modified, or deleted is recorded and can be viewed in the
Admin Audit Report.

8 www.admanagerplus.com
Delegation to help desk technicians:
ADManager Plus empowers help desk technicians to perform tedious and routine AD tasks that don't
require the dependency of administrators, thereby reducing their workload. You can create a single
technician or multiple technicians in one go. Each technician has a unique login ID, to which the delegated
domain will be mapped. Every technician should be configured to at least one role. Besides delegating AD
management and reporting, you can also delegate Microsoft 365 and Google Workspace management
and reporting tasks.

Service account:
Upon logging in to ADManager Plus, you can add AD domains in the Domain Settings section. You can
either use an account that belongs to the Domain Admins group (recommended) or a service account that
has been assigned all the sufficient privileges required by ADManager Plus. The credential you provide
while configuring the AD domain in the Domain Settings section is stored in the database.

Impersonate as admin:
When a technician does not have the necessary permissions in AD to carry out the delegated tasks, the
option Impersonate as Admin can be enabled. When enabled, the technician will be able to perform the
delegated tasks with the privileges of the user account that has been configured in the Domain Settings
or with the user account that has been configured to run ADManager Plus. The actions performed by
technicians using this option would be logged in the DC as if it was performed by the user account
specified in Domain Settings. However, a complete audit trail of the actions done by any user account
using ADManager Plus can be obtained from the Admin Audit report.

Authorization:
ADManager Plus verifies authorization for the actions, domains, OUs, groups and file servers delegated to
the technician before sending data to domain controllers. The tool displays only the authorized actions
while carrying out management tasks based on the roles assigned to the technician.

3.4 Microsoft 365 management and reporting

ADManager Plus requires MS Online or Azure AD PowerShell, along with a stable internet connection for
managing Microsoft 365 accounts.

For instance, if the administrator chooses to remove a license assigned to a specific Microsoft 365 user
using ADManager Plus, the tool will retrieve the account and license information from the product
database and call the configured REST API or construct a suitable PowerShell script. Once the script is
executed, the corresponding Microsoft 365 license will be removed for that user and the updated license
information of the user will be stored in the database and displayed on the console.

3.5 Backup and recovery

3.5.1 AD backup and recovery

ADManager Plus allows you to backup and recover deleted AD objects.
AD backup: With the AD backup feature in ADManager Plus, you can take full backups or incremental
backups and save up space and time. Upon initiating an AD backup in ADManager Plus, an LDAP query
will be constructed. The LDAP query is executed in AD, and all the changes made to AD objects since the
last backup cycle are identified. These values are then stored in the Elasticsearch database. The tool will
then display the list of all backed up objects.

ADManager Plus server

10 www.admanagerplus.com
AD Recovery: When any recovery action is triggered by the administrator, an LDAP query is generated
and the ADManager Plus server fetches the data to be restored from the Elasticsearch database. This
value is then restored to AD, and the result is displayed in the GUI.

ADManager Plus server

3.5.2 Google Workspace backup and recovery

Google Workspace backup: When a backup is initiated for Google Workspace, the web client sends the
request to ADManager Plus' server via HTTPS, which is handled by Google API services. ADManager Plus
fetches the sync token from the previous backup to identify the data modified since the last backup cycle.
All changes made are backed up and stored in the backup repository. A new sync token is generated and
stored in the SQL database to be used for the next backup cycle. The backup stored in the repository is
fetched and displayed in the web client.

4. High availability

If ADManager Plus is installed as a service, you can configure the tool to automatically start as soon as the
server starts. Web service availability can be ensured by enabling the high availability option. ADManager
Plus achieves this by employing a high availability architecture that designates a server to act as a standby
to the primary server.
The same database is used for both the servers, and at any given time, a single server will cater to
user requests and the other will be inactive.
Whenever the primary server runs encounters unplanned downtime, the standby server becomes
operational and takes control of components.

5. Rest APIs

ADManager Plus offers REST APIs to enable integration with other applications like help desk tools. These
APIs allow you to access ADManager Plus from other applications and perform necessary AD user
account management functions. Click here to know more.

6. Mobile applications

ADManager Plus can be accessed from anywhere at anytime using its iOS and Android applications. A
wide range of AD management and reporting actions are accomplished with the help of APIs.

7. Security measures against vulnerabilities

ADManager Plus takes stringent security measures during different phases of the development cycle to
mitigate security vulnerabilities. These measures are overseen by a security team exclusively meant to
diagnose and handle potential vulnerabilities in the product.

Our in-house security tool is one such measure to help identify and mitigate potential security
vulnerabilities in a product executable. It works by applying a set of rules and provides security reports
listing all the rules that were violated in the product executable. Additionally, an internal and external bug
bounty program has been put in place to report on the vulnerabilities in our suite of products.

13 www.admanagerplus.com
8. Confidentiality

ADManager Plus application has implemented the following measures to uphold the confidentiality of
user data:

ADManager Plus' database is password protected by default.

Database backup passwords are generated at the time of backup and can be configured in Privacy Settings
(Admin --> General Settings --> Security and Privacy --> Privacy Settings) in the tool.

Exported reports can be protected by password.

Only authorized users can carry out operations in ADManager Plus.

No user details are exposed without authorization.

Object name (Name of the object on which the action was carried out)

Object domain (Domain name of the object)

Status (Result of the task)

Additional details such as attribute values and request details

9. Integrity

ADManager Plus report data is fetched from Active Directory directly. To maintain the integrity of the
report data, the AD sync occurs every 10 minutes. The intuitive dashboard is updated on a daily basis. The
report data in ADManager Plus will have the same information as in the domain controllers. The tool will
also check values of non-replicated attributes such as lastlogonTime on each DC to find the most recent
one before displaying it.

10. Accountability

Audit logs maintain the details of all AD Management activities like password reset, user deletion,
creation/modification of user accounts, etc., performed using ADManager Plus. Besides these, audit
reports list the actions performed by help desk technicians. It provides details, such as what action was
performed on which object and the time at which it was performed.
