Symptoms

AD or LDAP groups retrieval might lead to /tmp overflow. The /tmp folder contains many garbage files ad_temp_* or ldap_temp_*, and the system is not operating as expected.

Impact

/tmp folder runs out of space. This might result in system instability overall. Any daemon that tries to store temporary data into /tmp will fail.

Conditions

-- AD Group Mapping agent or LDAP Group Mapping agent is configured for VPE. -- Groups updated multiple times by administrator at AAA AD/LDAP Server configuration page (groups tab).

Workaround

Write a script to remove /tmp/ad_temp_* and /tmp/ldap_temp_* files, add the script to crontab to be executed periodically.

Fix Information

AD or LDAP groups retrieval no longer leads to /tmp overflow.
