ManageEngine ADSelfService Plus: A Complete Guide to Self-Service Password Management

How to Deploy and Configure ManageEngine ADSelfService Plus in Your DomainDeploying and configuring ManageEngine ADSelfService Plus (ADSSP) in your Active Directory environment can significantly reduce password-related helpdesk tickets, empower users with secure self-service options, and improve overall security posture. This guide walks you through planning, installation, configuration, and best practices for a successful rollout in a domain environment.

Overview: What ADSelfService Plus Does and Why It Matters

ADSelfService Plus is a web-based self-service password management and single sign-on (SSO) solution for Active Directory environments. Key capabilities include password reset and unlock, multi-factor authentication (MFA) for sensitive actions, self-update of AD attributes, kiosk mode, and SSO to cloud and on-prem apps. Deploying ADSSP lowers helpdesk workload, reduces downtime, and enforces stronger authentication for identity-critical tasks.

Pre-deployment Planning

1. Environment assessment

   • Inventory domain controllers, AD forests, and trust relationships.
   • Note operating system versions, patch levels, and network topology.
   • Identify user populations (on-prem, remote) and service-level expectations.

2. Requirements and sizing

   • Server OS: Windows Server or Linux (check current ManageEngine documentation for supported versions).
   • Hardware: allocate CPU, memory, and disk based on number of users — e.g., small deployments (up to 2,500 users) can run on 4 CPU cores / 8 GB RAM; larger deployments scale proportionally.
   • Database: ADSSP supports embedded (default) database for small/medium deployments and external DBs (MS SQL, PostgreSQL) for high-availability and enterprise scale.

3. Network and security considerations

   • Decide where the ADSelfService Plus server will sit (DMZ for external access vs internal network).
   • Open necessary ports (HTTPS 443 by default; LDAP/LDAPS to communicate with AD).
   • Plan TLS/SSL certificate provisioning (use trusted certificates for production).
   • Prepare service accounts with required privileges (read/query AD attributes; perform password reset/unlock if delegated).

4. High availability and disaster recovery

   • Evaluate the need for distributed deployment, failover, and backup strategy.
   • For critical environments, use an external DB and consider installing a secondary ADSelfService Plus server in High Availability (HA) mode (if supported).

Installation

1. Download

   • Obtain the latest ADSelfService Plus installer for your platform from ManageEngine.

2. Install on Windows or Linux

   • Run the installer as an administrator.
   • Choose installation directory and select embedded or external DB option.
   • Configure initial admin credentials—store them securely.

3. Initial service and web console access

   • Start the ADSSP service.
   • Access the web console using https://:/adsspp or the default URL provided.
   • Import or configure SSL/TLS certificate for the web UI (replace the default self-signed cert).

Add and Integrate Active Directory Domains

1. Add domain(s)

   • In the ADSSP console, go to Domain Settings (or equivalent) → Add Domain.
   • Provide domain details: domain name, domain controller IP/FQDN, and port (LDAP/LDAPS).
   • Use a dedicated AD service account with delegated permissions. For password reset/unlock, the account must have “Reset password” and “Unlock account” permissions or appropriate delegation.

2. Test connection and synchronize

   • Validate connectivity to domain controllers.
   • Configure AD discovery and user import: decide between on-demand (users authenticate) and scheduled sync.
   • Map user attributes (sAMAccountName, mail, UPN) as needed.

3. Handling multiple forests/trusts

   • For multiple forests, add each domain separately and ensure trust relationships are in place for credential verification.
   • Configure cross-forest policies and attribute mapping consistently.

Configure Authentication and Registration Policies

1. User registration methods

   • Choose which registration options to offer: email verification, SMS, AD security questions, AD attributes, biometric integration, or CAPTCHA.
   • For SMS/email, configure SMTP settings and an SMS gateway/provider; verify sender addresses.

2. Self-service password reset (SSPR) workflow

   • Configure the steps users must complete to reset or unlock: number of authentication factors, required questions, or verification via email/SMS.
   • Set password policy checks to reject passwords that violate domain password policies.

3. Multi-factor authentication (MFA) settings

   • Enable MFA for registration and sensitive operations (password change, SSO).
   • Supported methods may include TOTP apps (Google Authenticator), SMS, email, security questions, and third-party authenticators—configure as appropriate.

4. Kiosk and offline scenarios

   • Configure kiosk mode for shared devices or helpdesk kiosks.
   • For remote users, enable secure external access (reverse proxy or publish via a secure gateway). Use strong TLS settings and IP restrictions if needed.

Configure User Self-Service Features

1. Password reset and unlock

   • Enable SSPR and set policies: number of attempts, lockout handling, notification settings.
   • Define role-based access: which groups can use self-service and which require additional verification.

2. Self-update of AD attributes

   • Allow users to update certain attributes (phone number, address, alternative email).
   • Map permissible attributes, and configure approval workflows if required.

3. Password policies and complexity checks

   • Enforce domain password policies and optionally add custom checks (history, blacklist).
   • Configure password expiration notifications via email or in-app alerts.

4. SSO and application access

   • Configure SSO for cloud and on-prem apps (SAML, OAuth, Kerberos-based SSO).
   • Add applications and test sign-on flows; map user attributes and roles for SSO claims.

Notifications, Reporting, and Auditing

1. Email and SMS notifications

   • Configure templates for registration, reset success/failure, admin alerts.
   • Ensure SMTP and SMS settings are tested and reliable.

2. Auditing and logs

   • Enable auditing for critical actions: resets, unlocks, admin changes.
   • Store logs securely and integrate with SIEM if required (Syslog or API integrations).

3. Reports

   • Use built-in reports: password reset trends, registration status, failed attempts.
   • Schedule regular reports for stakeholders and compliance teams.

Policies, Roles, and Permissions

1. Administrative roles

   • Create granular admin roles (read-only auditor, helpdesk operator, full admin).
   • Limit access based on the principle of least privilege.

2. User role policies

   • Define which AD groups have access to features (SSPR, attribute update, SSO).
   • Use group-based policies for targeting different user populations (e.g., contractors vs full-time employees).

3. Delegation of password reset rights in AD

   • If ADSSP uses a service account, ensure proper delegation in AD rather than giving broad domain admin rights.

Testing and Pilot Rollout

1. Pilot group selection

   • Start with a small pilot (helpdesk, IT, or a single department).
   • Validate all workflows: registration, password reset, unlock, attribute change, MFA, SSO.

2. Test cases

   • Include normal, edge, and failure cases: expired passwords, locked accounts, incorrect MFA, unreachable domain controller, cross-forest resets.

3. User training and documentation

   • Prepare quick-start guides, screenshots, and video walkthroughs.
   • Provide clear instructions for registration, resetting, and contacting helpdesk if needed.

Troubleshooting Common Issues

• LDAP/LDAPS connection failures: verify network connectivity, port access, and certificate trust.
• Incorrect permissions: check the AD service account delegation for reset/unlock rights.
• Email/SMS delivery failures: verify SMTP settings, sender reputation, and SMS provider credentials.
• SSO failures: confirm SAML certificates, assertion consumer URLs, and attribute mappings.
• High load or performance issues: review server sizing, enable external DB, and optimize sync frequency.

Maintenance and Best Practices

• Keep ADSelfService Plus updated with patches and new releases.
• Rotate service account credentials periodically and follow strong password policies.
• Monitor logs and set alerts for abnormal behavior (spike in failed resets).
• Use a trusted CA for TLS certificates and disable weak ciphers.
• Regularly review and prune attribute access and admin roles.
• Back up configuration and database regularly; test restore procedures.

Example Minimal Checklist for Deployment

• Prepare server and OS updates.
• Create and delegate AD service account.
• Install ADSSP and apply TLS certificate.
• Add domain(s) and validate connections.
• Configure registration, MFA, and SSPR policies.
• Test with pilot users and iterate.
• Roll out organization-wide and monitor.

Deploying ManageEngine ADSelfService Plus carefully—starting with planning, a controlled pilot, and incremental rollout—yields faster user recovery from password issues, reduces helpdesk load, and strengthens authentication across your domain environment.
