Issue/Introduction

Login issues occur with some users in the Production environment.

The error message with code -57 could be related and may be useful to explain the reason for this behavior.

WebLogic Application Server v10.3.6 which is configured with a TAI.

When any user logs in to the application running on WebLogic, the Siteminder ASA Agent authenticates and authorizes successfully this user, but sometimes the TAI verification fails with this error message:

Resolution

Ensure that the Apache Web Server's time and time for all other component machines are in sync with NTP and resolve the issue.
