In this time, I am using wiki 1.2 together with LDAP(MS Active Directory) authentication. Users's sAMAccountName is not always lowercase. The situation is similar as mentioned Srini Pulugurtha in
Before wiki 1.2 was ready to go to our production environment, I had to "fix" username handling. It means, I had to convert name from login page to lowercase together with sAMAccountName.
So I think, it would be great to add some property into xwiki.cfg which will indicate that username is case insensitive.
I think, this will be very usefull for all potencial wiki users, who want to use LDAP authentication via MS Active Directory.
Please consider this wish
I am ready to test this new functionality, if you are not using MS AD.
