[Samba] Broken pipe when using ssh with pam_smbpass.so migrate

[Simon Nagl]

Hello again,

today I tried to debug the problem myself.
After downloading the source code I noticed that pam_smbpass is actually outdated.
It is removed with samba version 4.4 which I am actually not using. 

I found the reason for that in commit the commit message:

Now I am wondering how to keep my samba and unix accounts in sync.
My goal is having one account for ssh and samba-login on one server while keeping the configuration as simple as possible.

Is it possible to use winbindd and the corresponding pam module to authenticate against the samba user database without running a ad-dc?

Also I would offer to help making https://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/pam.html better.
I am not sure where you discuss possible enhancements. Open a bug? At this mailing list?

Thank’s for your help,
Simon
