Logon to the Identity Authentication Service (IAS) Administration Console is failing with error: Sorry, we could not authenticate you. Try again. Using the forgot password link allows to reset the password and login. However, logging off and trying to logon again the same error is shown as previously. Only a password reset allows login again for just one user session.
The Troubleshooting log is showing the following error:
User authentication failed. Reason: Used logon identifier is not allowed; Identifier: [ <logon_identifier> ]
