Hi all, I'm currently working on this problem with Ian. It seems like ntlm_auth is handling the requests fine - [root@server] /usr/local/bin # ./ntlm_auth --username=ianb --configfile=/usr/local/etc/smb.conf password: NT_STATUS_OK: Success (0x0) It also works through squid when using wget [2005/11/08 17:15:09, 3] utils/ntlm_auth.c:check_plaintext_auth(292) NT_STATUS_OK: Success (0x0) Note that it says check_plaintext_auth though, when using a browser (e.g. IE) we see the following messages [2005/11/08 15:16:36, 3] libsmb/ntlmssp.c:ntlmssp_server_auth(606) Got user=[IANB] domain=[MASTERMIND] workstation=[IANB] len1=24 len2=24 [2005/11/08 15:16:37, 3] utils/ntlm_auth.c:winbind_pw_check(427) Login for user [MASTERMIND]\[IANB]@[IANB] failed due to [Wrong Password] Why is it using a different method? It seems like the problem only occurs when it doesn't use check_plaintext_auth. Is there anything we can do to learn more? Thanks for all the help so far Dave
