Re: AUTOFS + LDAP Doubt. /skole mount point or /skole/tjener/home0 mount point?
Thank you for your answer. I think I'm starting to learn how it works...
But....

Only one problem. I searched in 3 workstations and I don't find the
/etc/auto.master file!!!
I usually use the Klaus work (thank you very much Klauss) at
http://www.skolelinux.org/~klaus/newnotater....
In this page http://www.skolelinux.org/~klaus/newnotater/a3794.html I
suggest that workstations didn't use
/etc/auto.master file.
I'm a bit confused at this moment....
Anyway, can you send an /etc/auto.master example file?
