Module: wine Branch: master Commit: 72ffc3fad96478ee7565cd03aebfe5ebf6b93064 URL: http://source.winehq.org/git/wine.git/?a=commit;h=72ffc3fad96478ee7565cd03ae... Author: Rob Shearman <rob(a)codeweavers.com> Date: Fri Jan 25 14:05:31 2008 +0000 secur32: Move the detection of NULL credentials from AcquireCredentialsHandle to InitializeSecurityContext. Only use cached credentials if the credentials were NULL. Don't pass a domain into ntlm_auth when using cached credentials as ntlm_auth/winbindd should be able to figure that out. --- dlls/secur32/ntlm.c | 131 ++++++++++++++++++++++++-------------------------- 1 files changed, 63 insertions(+), 68 deletions(-) diff --git a/dlls/secur32/ntlm.c b/dlls/secur32/ntlm.c index 3dbdd83..7cb83ec 100644 --- a/dlls/secur32/ntlm.c +++ b/dlls/secur32/ntlm.c @@ -133,50 +133,6 @@ static SECURITY_STATUS SEC_ENTRY ntlm_AcquireCredentialsHandleW( static const char domain_arg[] = "--domain=";
