After update 0.57, I can't login using my sAMAccountName. I need to use my email.
If the Active directory account does not have email, login with sAMAccountName works.
In logs, I can see the search works:

LDAP ➔ Search.info Search result count 1 [... my user info printed are ok]

And after, I can see this:
[LDAPSync ➔ debug user { email: undefined, _id: 'ktb98PyMhbst8jFn5' }

Same for me. Only Email works after the update.

Try to disable LDAP Avatar Sync, worked for us.

Thanks @KervyN ! it works

[maxdwit]

Confirmed @KervyN Disable avatar sync fixed it for the moment.

Anyone can provide a LDAP server for tests?

[rodrigok]

What happens if you enable the Avatar Sync again?

[KervyN]

We were not able to log in

Disabling avatar Sync worked for us
