I'm trying to setup PAM authentification for SMTP client connection. So to authent for SMTP to send mail, using the same as the login to the host.
The log says:
2011-04-28 20:19:31 plain_pam authenticator failed for xxxx ([x.x.x.x]) [x.x.x.x]: 535 Incorrect authentication data (set_id=user)
2011-04-28 20:19:33 login_pam authenticator failed for xxxx ([x.x.x.x]) [x.x.x.x]: 535 Incorrect authentication data (set_id=user)
/etc/pam.d/exim:
auth required pam_unix.so
account required pam_permit.so
session required pam_permit.so
Any hints to look or activate some trace info to see what is failing ?
