Hi Lars,
thank you for your kind reply. I am using SuSE. I found the messages file under /var/log.
This is what it outputs:
Nov 20 18:37:34 dotlrn nsd: PAM unable to resolve symbol: pam_sm_acct_mgmt
Nov 20 18:37:34 dotlrn nsd: pam_radius_auth: unrecognized option 'debug^M'
Nov 20 18:37:34 dotlrn nsd: pam_radius_auth: Could not open configuration file /etc/raddb/server: Permission denied
It seams that it does not recognize the debug option but there must be something else wrong as well, don't you think?
Best wishes,
Nima
