From b531f40581f6b871c08643a0e9ef11f632de0363 Mon Sep 17 00:00:00 2001 From: Greg Hudson Date: Tue, 13 Dec 2011 00:53:56 +0000 Subject: [PATCH] krb5_server_decrypt_ticket_keytab wrongly succeeds If krb5_server_decrypt_ticket_keytab doesn't find a key of the appropriate enctype in an iterable keytab, it returns 0 (without decrypting the ticket) due to a misplaced initialization of retval. This bug causes kinit -k to claim "keytab entry valid" when it shouldn't.
