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.
