1. Check the vcommander.log file for entries similar to:

   Authenticating user cnalaar  
   Ldap login as cnalaar failed  
   javax.security.auth.login.FailedLoginException: Cannot find user's LDAP entry
   

2. Update Commander LDAP configuration:
   • Go to Configuration > System Configuration, then Authentication tab.
   • Select the LDAP directory service and click Edit.
3. Click Next until you reach the Identity page.
4. Disable the Anonymous Search option.
5. Click Next and Finish to save your changes.

Outcome

Disabling anonymous searches ensures Commander can authenticate users by properly querying the LDAP server. LDAP users will now be able to log in successfully.
