Hi ,

In one of our server  , version rhel5.2 , kernel 2.6.18-92.el5xen. 86_64. We 
are  using pam_tally2.so module in the system-auth file. 

To unlock the useid, we use  pam_tally --reset --user <user>.

But very recently while  unlocking one user with pam_tally2 (as pam_tally2 is 
being used) , found the report  is as follows,

  pam_tally2 --user xxx
        Login           Failures Latest failure     From
        yyy               8    06/08/10 04:39:51  unknown

For user  xxx it is giving the output of user yyy.  While checking the yyy user 
in /etc/password , found this user has  /bin/nologin to the server.


both the users  xxx and yyy are local.

Tried to duplicate  the scenario creating different userid. But I am seeing now 
pam_tally2 is reporting the correct user now. 

So what will be the reason behind it . Is it the reason that user yyy  had  
login access  and it was locked and then this user's access has been disabled 
with  nologin in /etc/passwd.?  and when we went to unlock the user  xxx , it 
asked for  yyy and it reset the password  of yyy? 

Will be appreciated for explanations.

thanks in advance
