Actually login information is stored in "/var/log/auth.log".  The Xorg logs 
are simply pertaining the to X server, not the login manager (xdm/kdm/gdm..).  
The OP needs to find lines like this (successful login on my lappy):

Mar 21 09:47:07 hostname kdm: :0[7998]: (pam_unix) session opened for user 
myuid by (uid=0)

Here are two more.  This first one has a correct user ID but a bad password:
Mar 21 10:22:34 hostname kdm: :1[15733]: (pam_unix) authentication failure; 
logname= uid=0 euid=0 tty=:1 ruser= rhost=  user=myuid

...and this one has a bogus user ID:
Mar 21 10:26:56 hostname kdm: :0[8188]: (pam_unix) check pass; user unknown

The ":0[12345]:" is actually the display number followed by the X server's 
PID, ie:
:DISP_NUM[PID]:

So to generate these log lines, you can see I had two X servers running - one 
to write this e-mail, the other to enter bogus login details ;)  Ordinarily, 
you'd only have the one.

HTH,

James
