It is possible the integration of MWG7 with NT Servers?. The customer has a NT Server. ¿There are some problem with the browsers?
generally you can try using NTLM v1 in conjunction with NT servers. I should work. We haven't specifically tested this setup as NT is even not supported by Microsoft anylonger. But as NTLM comes from these days, it should work. For browsers, all browsers on windows that I know support NTLM.
