+Subject: [PATCH] krb: recreate ccache if it was deleted
+
+https://fedorahosted.org/sssd/ticket/1512
+
+If directory where a ccache file was stored was missing and user
+was still logged in, we erroneously considered the ccache file
+still active. Thus the ccache file was not recreated and user was
+unable to login.
