Hello Again, (Alex)
This time i could log in via the text mode and GUI mode of the console in my ldap server machine.
what i did is :
1. mkdir /home/jmaan
2. chmod 700 /home/jmaan
3. chown jmaan /home/jmaan
4. chgrp jmaan /home/jmaan
then same i did with the test user -ldapusr
But now when i tried doing with other users (in my ldap user like say for an exmple the user-aracd, i could not the change the group owership as i could do with the users jmaan and ldapusr.
Now the question is why did it behave like this ?
In no ways the users -jmaan or ldapusr was a member of the group jmaan or ldapusr, then how could i change their group successfully and other users like say to cite here as an example--the user "aracd".
May i know i had been wrong somewhere ?
Here are the transcripts of the commands:-
[root@authdns home]# chown aracd /home/aracd
[root@authdns home]# chgrp aracd /home/aracd
chgrp: invalid group `aracd'
[root@authdns home]# ls -l /home/aracd
total 0
[root@authdns home]# ls -l aracd

[root@authdns home]# ls -l

This is very basic linux admin stuff, change the owner of the directory !
read up on chown, chmod and chgrp
you can try man or google
