Re: OpenLDAP + autofs integration

[Tomas Maly <malyprogservices@flashmail.com>]

What I did is created my own init script that would search underneath
"ou=Automount,o=domain.com" for any ou's (with a scope of one). I then
named that ou as the base path in which entries below it would mount. I.E.,
if I had an entry named "cn=tmaly,ou=home,ou=Automount,o=mvista.com", it
would mount the value of automountInformation under /home/tmaly. I'm
actually surprised to see this method. I might want to try it myself. The
question is, do I worry about propogating the init script to everyone (if
I go with my original idea) or do I go with this idea, and worry about
progating auto.master? Either way, something needs to be propogated. The
better choice is probably that which is more static. I might want to create
a new mount point for people to use. It's easier for people to simply make
the directory rather than make the directory and make sure that auto.master
is updated. You decide.
