with passdb ldap i guess. ---Aki TuomiDovecot oy -------- Original message --------From: Mark Foley <mfoley@ohprs.org> Date: 03/12/2017 21:18 (GMT+02:00) To: dovecot@dovecot.org Subject: Re: Howto authenticate smartPhone via Active Directory Yes, you are right. This link: https://www.redips.net/linux/android-email-postfix-auth/#section2 shows:
passdb pam { }
used for authenticating Android. Problem #1 is that Slackware does not ship with PAM and the AD/DC Samba4 does not use it. It is used on Slackware for a domain member, but I'm not sure I should try configuring PAM on the AD/DC.
Is there some otherway I can get authentication using domain credentials besides pam? the phone can send user and password.

Actually you are authenticating gssapi clients from ad and everyone else from shadow. maybe you need to configure pam module? ---Aki TuomiDovecot oy

I have a Samba4 Active Directory server. Dovecot authenticates AD Users with domain credentials using GSSAPI (Thunderbird client). I believe I have Dovecot set to attempt authentication via shadow first and. failing that, it does authenticate via GSSAPI.
Smartphones connect to Dovecot via port 143 and SSL. They are not domain members so if the shadow authentication fails, no other methods are tried and no connection is made.
What can I do with my dovecot config to fix this?
