I have a gitlab-ce installation on Debian jessie with LDAP integration.
After upgrading to 9.0 I cannot login anymore. I had to remove the cookies to even get to the login page. When I try to login I get:
Could not authenticate you from Ldapmain because “Undefined method `ghost?’ for #user:0x007fb152d29050”.
What can I do to diagnose/fix this?
