I've update a 4.4.9 linux install to 5.1.3 Windows and switched it to a different ldap server. Everything appeared to be working fine. Then I tried out the ignore_case option. I didn't catch that it was generating new lowercase accounts at first, until testing with a user and realizing she was effectively working from a new account (no images). So I shut down the server, turned ignore_case off, and restored a previous db backup to eliminate the duplicate account.
When we tested again I can log in and she could not. Looking in the blitz log there were exceptions thrown when she tries to log in. So, I shut down the server, turned_ignore case back on, went into the experimenter table, and changed all the usernames to lower case. It works great for me and another admin, but it still throws errors when the user tries to login. Strangely, my account was mixed case and after renaming accounts I didn't have any problems.
I've tried attaching an excerpt from the blitz log to show the errors, but I get "The extension is not allowed." no matter what I try. Any ideas how to fix this? Is there something else that needs to be purged? Who can I forward the log excerpt to? Thanks!
