prompting for username again ?????

Which authentication schemes have you enabled?  MD5?  Shadow?  Is this a fresh 7
install, or an upgrade from a previous release?  Are there any relevant messages
in /var/log/messages?

Hi

to reply :

I have both shadow and md5 enabled similar to my previous 6.2 installation
(which was sucessfull). I also selected LDAP & KEREBOS on that screen during 
install which was new to me and not available to select on 6.2.

This was not a upgrade but a fresh install with formatting.

I checked /var/log/messages through vi and found a lot of messages, what to 
look for is not clear for me but I noticed the following and hope it can 
assist :

- a lot of stuff indicating disabled ,removing . starting with AMANDAIDX 
  I also noticed the following disabled & removed :
  - eklogin
  - exec
  and plenty other stuff ....

- I also found this in /var/log/messages?
  - Localhost PAM_unix [904] : authentication failure Login (uid = 0) ->
    root for system auth services
  - Localhost PAM_unix [912] : check pass; user unknown
  - Localhost PAM_unix [912] : authentication failure Login (uid = 0) ->
    r045 for system services 

Someone in my newsgroup also asked me to check /etc/securetty for listings of 
tty1 & tty2 ... etc.
I checked it and found the following :
vc/1 to vc/11 &
tty1 to tty11.
 
Thanks 
Julian

Hi 

I couldn't wait anylonger to get up & running as my online course and usergroup
was starting to gain too much on me.
So I decided to reinstall (would have liked to be able to fix instead, unlike 
windows....)

Anyways, I reinstalled and the only difference was not to select LDAP & KEREBOS.
NIS I never selected the first time around anyway!
So, the only items selected during install was md5 & shadow......

The system seems ok now and I am able to login....

Thanks for the assistance,,,(just not happy that I still don't understand what 
the problem was)

Thanks again
Julian

Hi

Could you tell me if ever there was a conclusion to this problem or maybe still 
working on a solution ?

Thanks 
Julian

A "user unknown" error usually means that there was some problem accessing the
/etc/passwd file, either because it was somehow corrupted or removed.  We were
never able to reproduce it (my own workstation uses both LDAP and Kerberos with
our internal servers, and this hasn't happened).
