Hello,
We have had Active directory sync up and running for a few months now on Alfresco 4.2.c. Everything seemed to be working fine until I noticed that users were logging in using their email addresses and Alfresco was creating a separate user for them. For example, I log in using my active directory account and everything is as it should be. I log out and log in using my email address and domain password, and it creates/log me in to a new account. I would like to make it so that logging in with email addresses does not work, but I am not sure how to accomplish that. Any help would be greatly appreciated.
