Troubleshooting "Authentication failed. 53" or "Authentication failed. 67" when attempting to login the TPAM web interfaces -
Beschreibung
Error "Authentication failed. 53" or "Authentication failed. 67" when attempting to login to the TPAM web interfaces. This occurs for users when using WinAD external authentication (AD credentials), local authenticated users can login without error. AD users are unable to logon. -
Ursache
The error means TPAM is unable to communicate with the Windows Active Directory server to authenticate the user. -
Lösung
Troubleshoot why the connection to Windows Active Directories servers is failing:
1. From /tpam | Users & Groups | Manage UserIDs locate the user and go into the "Details" tab, note the "Source"2. From /admin | System Status/Settings | External Authentication | WinAD Config, select the correct (Source from above) system. Note the "Server address".
3. If a "DNS Name" has been entered, ensure this can be resolved by DNS.This can be done from /tpam | Management | Network Tools | Nslookup
4. To authenticate users, TPAM connects to the AD server using TCP/389, a telnet test can be used to validate connectivity.
From /tpam | Management | Network Tools | TelnetTest, enter the system name, and enter 389 as the port.A message such as "Telnet connection test to x.x.x.x on 389 completed in x.x seconds" means it has successfully connected.
