Description Martin Kosek 2015-03-04 08:57:05 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/sssd/ticket/2592

Function ldap_child_get_tgt_sync in ldap_child.c is creating file ccname_file_dummy but it is not unlinked if there is an error.  This can cause a lot of these files to be created using up inodes on the file system.
