Description Simo Sorce 2013-11-18 15:44:04 UTC

The keyring caches do not have an explicit timeout set.
Keyrings should be made to expire when the credentials they contain expire to avoid keeping kernel memory/tmpfs busy with useless data.

It is important on  big systems that have many users and all of them acquire kerberos credentials.

A patch to implement this feature is available upstream in commit: 29e60c5b7ac0980606971afc6fd6028bcf0c7f0f
