In Alfresco 5.2 one of the ldap user is not able to login. He was able to login in the past. Also user can login to test environment using same ldap password. Can someone please suggest if there in anything changed in 5.2 Authentication method.
No change in authentication method in 5.2, but some security helpers are activated by default for brute force attacks. So in some cases, if the user fails repeatly when login, the account may be temporaly disabled.
