Hi I am running squid(2.6.stable9) with ntlm authentication and that is working fine for any http access. However while I am trying connect any instant messaging (Yahoo messenger, MSN) through the proxy, connection is getting failed. Log shows: [2007/04/12 14:40:39, 1] libsmb/ntlmssp.c:ntlmssp_update(267) got NTLMSSP command 3, expected 1 [2007/04/12 14:40:41, 1] libsmb/ntlmssp.c:ntlmssp_update(267) got NTLMSSP command 3, expected 1 [2007/04/12 14:40:47, 1] libsmb/ntlmssp.c:ntlmssp_update(267) got NTLMSSP command 3, expected 1 [2007/04/12 14:41:12, 1] libsmb/ntlmssp.c:ntlmssp_update(267) got NTLMSSP command 3, expected 1 2007/04/12 14:41:15| Preparing for shutdown after 13 requests (Error logs are somewhat similar to bug 1873 - fixed in squid 2.6.stable8) Adding more debug statements in src/auth/ntlm/auth_ntlm.c file I have found: Sequence is as follows: Failure case: authenticateNTLMStart authenticateNTLMAuthenticateUser: auth state ntlm none authenticateNTLMAuthenticateUser: Locking auth_user from the connection. authenticateNTLMAuthenticateUser: need to challenge client authenticateNTLMAuthenticateUser: auth state ntlm failed authenticateNTLMHandleReply:: reply = NA NT_STATUS_INVALID_PARAMETER Success case: authenticateNTLMAuthenticateUser: auth state ntlm none authenticateNTLMAuthenticateUser: Locking auth_user from the connection authenticateNTLMAuthenticateUser: need to challenge client authenticateNTLMAuthenticateUser: auth state challenge with header authenticateNTLMHandleReply:: reply = AF suman However this is working fine with squid 2.5.stable11(old enough)... Any help will be highly appreciated. With regards Suman
