Troubleshooting: Invalid User ID or Password Error for a Subset of Users (AD Logon Restrictions)

Version Affected: All
 
 

Overview

When logging in to SecureAuth Identity Platform, most users authenticate successfully, but a specific subset of users always fail with an Invalid User ID or Password error, even though they are typing the correct password.

Cause

The affected users' Active Directory (AD) accounts have logon restrictions applied, limiting which machines they are allowed to log on to.

When SecureAuth Identity Platform validates a user's password, AD counts this as a logon attempt from the IdP server itself (on-premises or hybrid deployments) or from the Connector machine (cloud deployments). If that server is not on the affected user's allowed logon list, AD rejects the logon attempt, which SecureAuth Identity Platform then reports as an invalid password.

Resolution

Work with your AD administration team to add the SecureAuth server(s) to the allowed logon list for each affected user:

1. Open Active Directory Users and Computers (ADUC).
2. Find the affected user and open their properties.
3. Click the Account tab, then click Log On To
   .
   
4. Type in the name of the SecureAuth IdP server or SecureAuth Connector server.
5. Click Add.
6. Repeat for each server the user needs to be able to log on to.
   
7. Click OK to save the changes.

Special Considerations

Adding a server to this list only allows AD logon validation to succeed from that server. Users can still be prevented from logging on to these servers directly (for example, over Remote Desktop) by using a Group Policy Object (GPO) or Local Policy to set Deny log on locally.
