Afternoon,
We are receiving an odd error in our 3.5.3 environment. This occurs when users login with a space character in front of there username. It causes a CAS unavailable error instead of being caught and handled in a more user friendly manner.
Has anyone else seen similar behavior and if so how did you resolve it. Our user data is stored in LDAP and we do have a a few bits of custom code but it is called after this exception. We are also running the lppe.
Thank you for your input and I would be happy to send more detailed configuration information if requested.
