some (very little) progress: I've checked the permissions and changed 
owner of kdm to root:

# ls -l /opt/kde/4.3.4/bin/kdm
-rwxr-xr-x 1 root root 157113 jan 29 19:25 /opt/kde/4.3.4/bin/kdm

still the same problem, but not exactly the same messages in 
/var/log/auth.log

Feb  2 21:34:51 localhost kcheckpass[1671]: pam_warn(kde:auth): 
function=[pam_sm_authenticate] service=[kde] terminal=[:0] 
user=[kde-devel] ruser=[<unknown>] rhost=[<unknown>]
Feb  2 21:34:51 localhost kcheckpass[1671]: Authentication failure for 
kde-devel (invoked by uid 1009)
