XDM and authenticating users

["Tero Ripattila" <tero_(_at_)_ripattila_(_dot_)_com>]

Hello all,

How does XDM authenticate its users ? I know that in many linuxes this is  
done via PAM, but it's different with OpenBSD due to many reasons e.g. PAM  
is not supported in OpenBSD.

The actual problem is that regular users cannot login to a -current server  
using XDM, but somehow root can. All of these users are authenticated  
against FreeRadius so their login class is set to "radius". But when I  
tail -f the FR log file during login procedure, nothings shows up there,  
which makes me think XDM does not autheticate users against FR, which is  
used e.g. when I login locally or use ssh.

Any pointers or suggestions ?

Best regards,
Tero
