Description Vincent Danen 2012-06-13 18:25:01 UTC

Due to a problem with the patch used to correct a problem with LDAP servers not correctly returning an opaque cookie to check for additional results when getting paged results from a server on 64-bit PowerPC and IBM System z platforms (RHBA-2012:0264), it was possible for a user to cause a denial of service of the autofs service.  While this may not impact mounts that have already been mounted (other than preventing mount expiration), it will prevent any future mount requests from being processed until autofs is restarted.
