From 61bedb4263a73121bde3fb18295bc0abc4ccbcb2 Mon Sep 17 00:00:00 2001 From: Steven Danneman Date: Thu, 26 Feb 2009 17:47:32 -0800 Subject: s3: fix guest auth when winbindd is running This fix is very subtle. If a server is configured with "security = share" and "guest ok = yes" and winbindd is running authorization will fail during tree connect. This is due to our inability to map the guest sid S-1-5-21-X-501 to a uid through sid_to_uid(). Winbindd is unaware of the hard coded mapping between this sid and whatever uid the name in lp_guestaccount() is assigned. So sid_to_uid() fails and we exit create_token_from_username() without ever calling pdb_getsampwsid() which IS aware of the hard coded mapping. This patch just reorganizes the code, moving sid_to_uid() down to the block of code in which it is needed, avoiding this early failure. --- source3/auth/auth_util.c | 14 +++++++------- 1 file changed, 7 insertions(+), 7 deletions(-) diff --git a/source3/auth/auth_util.c b/source3/auth/auth_util.c index 1f00e22a3c..c39aa8501d 100644 --- a/source3/auth/auth_util.c +++ b/source3/auth/auth_util.c @@ -806,7 +806,7 @@ NTSTATUS create_local_token(auth_serversupplied_info *server_info) } /* - * Create an artificial NT token given just a username.
