[Proftpd-user] SFTP + PAM + winbind

[Mathias M. <ma...@gm...>]

Hello,
 
I'm trying to setup an SFTP server on a RedHat 9 machine where users authenticate with winbind.
 
I have those settings enabled:
        SFTPPAMEngine on
       SFTPPAMServiceName proftpd
       AuthOrder mod_auth_pam.c mod_auth_unix.c
 
So local users can also connect (mostly for tests)
 
My current proftp PAM file looks like:
#%PAM-1.0
session    optional     pam_keyinit.so force revoke
auth       required     pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed
auth       required     pam_shells.so
auth       include      password-auth
account    include      password-auth
session    required     pam_loginuid.so
session    include      password-auth
 
Local users can connect (I guess thanks to mod_auth_unix.c)
Network users cannot.
I tried replacing password-auth with system-auth but that did not  help.
 
My guess is that some changes are needed in the PAM config file, but I have no clue what to change, and with which value. 
 
Any help welcome.
