I am having problems with mod_auth_ntlm_winbind. The httpd error_log shows an NT_STATUS_INVALID_PARAMETER error when I try to log in from browsers (firefox, ie). Winbind seems to be functioning properly as I can start smb and log in via smbclient. wbinfo and getent work well also. Use NTLMv2 switch is on for the server (windows server 2003). What am I doing wrong? -drew == httpd.conf =<Directory "/tmp/test"> Order allow,deny Allow from all AuthName "Domain Logon" NTLMAuth On NegotiateAuth On NTLMAuthHelper "/usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp -d9" NegotiateAuthHelper "/usr/bin/ntlm_auth --helper-protocol=gss-spnego" NTLMBasicAuthoritative On AuthType NTLM AuthType Negotiate Require valid-user </Directory> == error_log =[Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(1018): [client 10.0.1.14] doing ntlm auth dance [Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(482): [client 10.0.1.14] Launched ntlm_helper, pid 17034 [Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(652): [client 10.0.1.14] creating auth user [Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(703): [client 10.0.1.14] parsing reply from helper to YR TlRMTVNTUAADAAAAGAAYAGIAAAAYABgAegAAAAAAAABAAAAADAAMAEAAAAAWABYATAAAAAAAAAAAAAAABYIIAGQAcgBlAHcAaQBkAHMAYQBuAGYAZQByAG4AYQBuAGQAbwAkv/0BQK1sfAAAAAAAAAAAAAAAAAAAAACqF7oNvIilkIv2m3p/nQymm2TFvtxyGHM=\n [2006/11/27 16:36:10, 5] lib/debug.c:debug_dump_status(366) INFO: Current debug levels: all: True/9 tdb: False/0 printdrivers: False/0 lanman: False/0 smb: False/0 rpc_parse: False/0 rpc_srv: False/0 rpc_cli: False/0 passdb: False/0 sam: False/0 auth: False/0 winbind: False/0 vfs: False/0 idmap: False/0 quota: False/0 acls: False/0 [2006/11/27 16:36:10, 1] libsmb/ntlmssp.c:ntlmssp_update(252) got NTLMSSP command 3, expected 1 [Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(741): [client 10.0.1.14] got response: NA NT_STATUS_INVALID_PARAMETER [Mon Nov 27 16:36:10 2006] [debug] mod_auth_ntlm_winbind.c(765): [client 10.0.1.14] user not authenticated: NT_STATUS_INVALID_PARAMETER
