samba - Jul 2004 - failure running an at job from a root preexec

Hi folks,

I'm having a problem queuing an 'at' job from a root preexec.

I have a shell script which queries LDAP for per-user quota information and sets
the local filesystem quotas accordingly. This runs, and runs fine, out of the
root preexec on our users home share.

But we bin running a server with broken quotas for a while, and had to turn
quotas off.

We're ready to try again now, but most of our users are WAY over quota. So
we're gonna set their hard limits above current usage in LDAP, and
they'll get seven days grace from when they next log in. However, that will
leave the LDAP stored hard limits artificially high. So I want to drop an
'at' job in the queue, the first time a user logs in to the new server,
that will reset the user's limits in LDAP to what they were.

But I can't queue even a simple at job from a pre-exec script.

I can queue jobs manually no problem.

I drop the lines:

wall "$1 LOGIN"
/usr/bin/at now + 1 minute /root/atjob

on the end of my preexec script.

/root/atjob exists and contains:

wall "JOBJOB"



I use smbclient to access the home share, I get the wall output from the preexec
fine, but the job doesn't get queued.

Am I missing something here. ( Not many points for that one, I clearly AM
missing something )
If so, what?


Alternative approaches to this for solving the wider problem would be welcome
too.

Hope someone can help. I could do with implementing this before Monday. Gulp.

Oh I am such a fool.

Obviously, I missed the 'f-' off the at command line.

Sorry.
