Linux ID command
Hello,
I have ldap user, the user's UID value differs between two different servers, Please help me to understand why this happens.
[root@esg-dev~]# id lstarn
uid=80279(lstarn) gid=1091(web_dev) groups=1091(web_dev)
[root@linuxconsole ~]# id lstarn
uid=1(bin) gid=1(bin) groups=1(bin)
[root@linuxconsole ~]# grep lstarn /etc/passwd
[root@linuxconsole ~]# grep bin /etc/passwd
root:x:0:0:root:/root:/bin
bin:x:1:1:bin:/bin:/sbin/n
Both linux host esg-dev and linuxconsole are part of ldap.

here is the output
[root@linuxconsole ~]# getent passwd lstarn
bin:$1$tApqDl$5/wR5/6.9YD3
[root@linuxconsole ~]# getent passwd lstarn
bin:$1$tApqDl$5/wR5/6.9YD3
This problem occurs only on one particular server that is 'linuxconsole" server, same id works fine on other servers.
output from working server.
getent passwd lstarn
lstarn:*:80279:1091:Lauren
output from working server.
getent passwd lstarn
lstarn:*:80279:1091:Lauren
Check whether same id being used by any local user already if yes then pls modify it something else to make it work properly...

I'd say that something is badly wrong with your authentication configuration
User logs in as UID1 and automatically is owner of all systems' binary files.
