I'm trying to get mod_auth_ntlm with apache2 to work but it refuses to do so. ntlm_auth does work if I use the commandline argument. The error I got is: [2009/01/13 13:07:09, 5] lib/debug.c:debug_dump_status(391) INFO: Current debug levels: all: True/10 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 locking: False/0 msdfs: False/0 dmapi: False/0 [2009/01/13 13:07:09, 10] utils/ntlm_auth.c:manage_squid_request(2081) Got 'YR TlRMTVNTUAABAAAAB7IIoggACAAuAAAABgAGACgAAAAFASgKAAAAD1NJTU1FTFNUUk9FSEVS' from squid (length: 75).

The config part in apache2 looks like this: AuthName "NTLM Authentication thingy" NTLMAuth on NTLMAuthHelper "/usr/bin/ntlm_auth -d10 --helper-protocol=squid-2.5-ntlmssp" NTLMBasicAuthoritative on AuthType NTLM require valid-user I'm using OpenSuse 10.2 x86_64 with the newest updates. apache2-2.2.3-26 samba-3.0.23d-19.14 I guess the problem lies with winbindd_priviledged but when I set chmod 777 winbindd stops working. I allready chown root.www on winbindd_priviledged but that didn't seemed to help at all.
