Yes, it's possible to do this. But not possible using auth_bind. You are going have to login using an administrator account, then do an ldap search for the email address, then authenicate against it. Using auth_bind requires you to know the username before you login.

Just need to change passfilter to do a ?proxy_email? or what it's called for ad

Hi, many thanks for your reply.

Active Direcotry doesn't return the userPassword in

pass_attrs = uid=user, userPassword=password

so the password supplied by the user can't be validated.

I used this configuration

auth_bind = no pass_attrs = mail=user, userPassword=password pass_filter = (& (objectclass=User) (objectCategory=Person) (mail=%u)) default_pass_scheme = MD5

and although the ldap query located the user it complains with the following:

No password returned (and no nopassword)

Any ideas? Dimitrios

Hi all!

Is it possible to authenticate against Active Directory, using the whole e-mail address and not the user part (%n), so that if you support mutiple domains, all users should authenticate with their e-mail addresses.

I use auth_bind_userdn = DOMAIN \ %u but somehow the *mail* attribute of Active/LDAP should be employed.

thanks in advance Dimitrios Karapiperis

That would of been my next guess, to see if you could lookup the
proper user, then attempt a login via that. Just causes extra ldap
traffic.

Hi I just solved it using authentcation binds auth_bind = yes pass_attrs = mail=user pass_filter = (& (objectclass=User) (objectCategory=Person) (mail=%u))

Active Directory, as far as I know, by no means exposes users
passwords to third party applications or services.

Thanks in advance Dimitrios
