Please help: failed to open PAM security session

[snk]

Hi to all

i got problem with making admin's backup by cron from Admin Level:


May 11 20:30:01 host crond[7222]: Authentication service cannot retrieve authentication info
May 11 20:30:01 host crond[7222]: CRON (diradmin) ERROR: failed to open PAM security session: Success
May 11 20:30:01 host crond[7222]: CRON (diradmin) ERROR: cannot set security context

i've check all permission and googled but not found any solution how to fix this issue.

If i make backups by click "Now" all working fine, but from cron not.

Can somebody help me with this ?

Thanks.

Hello,

I've never seen that error before, so I couldn't really tell you what's up...
However there are a few things you can try to straighten out cron for the dataskq commands in this guide:
http://help.directadmin.com/item.php?id=107

The backups created by DA are stored in the cronjobs for user "diradmin", which can be viewed with:
crontab -u diradmin -lso make sure that's all there... past that, check /var/log/cron and /var/log/messages.

Hi John,

Thanks for reply.

I have checked all things from http://help.directadmin.com/item.php?id=107
all is fine.

crontab for diradmin user:


# crontab -u diradmin -l

30 20 * * * echo -e "action=backup&id=1&owner=admin" >> /usr/local/directadmin/data/task.queue.da; /bin/chmod 600 /usr/local/directadmin/data/task.queue.da


/var/log/messages doesnt have any error related to cron or D.A.
/var/log/cron log:

May 11 20:29:01 host crond[8759]: (root) CMD (/usr/local/directadmin/dataskq)
May 11 20:29:01 host crond[8760]: (root) CMD (/usr/local/ddos/ddos.sh >/dev/null 2>&1)
May 11 20:29:01 host crond[8761]: (root) CMD (/usr/local/sbin/bfd -q)
May 11 20:30:01 host crond[9137]: (root) CMD (/usr/local/directadmin/dataskq)

May 11 20:31:01 host crond[9616]: (root) CMD (/usr/local/directadmin/dataskq)


But if i run from console

echo -e "action=backup&id=1&owner=admin" >> /usr/local/directadmin/data/task.queue.da; /bin/chmod 600 /usr/local/directadmin/data/task.queue.da

no errors and backups created.
PS. cron seems to work good, because i didn't get any emails from my customer about cron jobs

i'm use CentOS 5.1 and DA 1.31.4

Update.

Problem fixed.
user diradmin was not present in file /etc/shadow.
After adding diradmin in /etc/shadow all work without error.
