From be1dfff02d562e42a7847bd02fed8538630d3f41 Mon Sep 17 00:00:00 2001 From: Dan Sledz Date: Mon, 2 Mar 2009 16:50:19 -0800 Subject: It appears that the first time we see a uid/gid that winbind can't map, we end up returning the null sid instead of falling back to the legacy code. Next time through the code we'll hit the negative cache and do the right thing, but we still fail the first time. If we fail the winbind id to sid mapping, call the legacy version. This catches the case where we don't have a negative cache entry for the mapping. This is better than returning the NULL sid to the caller. --- source3/passdb/lookup_sid.c | 36 ++++++++++++++++++++++-------------- 1 file changed, 22 insertions(+), 14 deletions(-) (limited to 'source3/passdb/lookup_sid.c') diff --git a/source3/passdb/lookup_sid.c b/source3/passdb/lookup_sid.c index 53845117e2..10ff36d51b 100644 --- a/source3/passdb/lookup_sid.c +++ b/source3/passdb/lookup_sid.c @@ -1308,13 +1308,17 @@ void uid_to_sid(DOM_SID *psid, uid_t uid) if (!ret || expired) { /* Not in cache.
