Thread:Extension talk:LDAP Authentication/"Failed to connect", but only for certain users/reply (2)

User B has a password distinct from his username, so that's not the problem.

Regarding those settings:

1. Out of curiosity, I commented them out, just to see what would happen. That was sufficient to let use B log in successfully! Woo! Now I'm trying to figure out why...

2. I set those because I wanted the user's email in LDAP to be updated if the user changes it in his prefs in MW. Is that not the right way to go about it?
