== Policy Server log ==
[1853/4086664048][Tue May 10 2016 11:03:34][SmDsLdapFunctionImpl.cpp:494][ERROR][sm-Ldap-00770] (AuthenticateUser) DN: 'uid=wonsa03,dc=support, dc=com' . Status: Error 49 . Invalid credentials
By design, the error is logged when the failed login attempt count tracked by the SMTRYNO cookie >= to the limit defined with smretries directive in the login form.
In customer case, the smretries was set to 1. Hence, whenever user failed to be authenticated, the error is invoked. Hence, the error is expected and it does not impact the web agent operations.
To avoid the error, set smretries to 0, meaning to say user has unlimited login attempts unless limited by password policy.
