Error 500 after authentication

Hi, I configured the LDAP auth and that seems to be ok but after login I’ve got a crash:

Any explanation to help me to fix this ?

Thanks a lot !

Yep, that was the missing conf. Now I get a new error, but it’s not ldap. Thank’s @dhirschfeld

I see the same thing - but with a different error. Python 3.6, CentOS 7.5, up to date. Note that prompt-toolkit is not up to date because I’m seeing the same issue everyone else is - prompt-toolkit v 2 is broken.
