Re: [PERDITION-USERS] NTLM Auth

Hello list, I'm in the process of deploying a perdition imap proxy to an exchange server. ATM there is a M$ proxy server installed that i wish to replace. All clients, Outlook in a vast majority, have SPA enabled that translates to NTLM auth. I have changed the CAPABILITY string to meet exchanges CAPs and i'm also not doing any authentication_in, i.e. all auth is performed in the backend exchange server. ... But it's not working. I can see in the logs the following: Dec 7 11:16:10 mail-proxy perdition[5863]: SSL connection using AES256-SHA Dec 7 11:16:10 mail-proxy perdition[5863]: SELF: "* OK IMAP4 Ready mail-proxy 0001e283\r\n" Dec 7 11:16:10 mail-proxy perdition[5863]: CLIENT: "1 capability\r\n" Dec 7 11:16:10 mail-proxy perdition[5863]: SELF: "* CAPABILITY IMAP4 IMAP4rev1 AUTH=NTLM AUTH=GSSAPI AUTH=PLAIN IDLE NAMESPACE LITERAL+\r\n" Dec 7 11:16:10 mail-proxy perdition[5863]: SELF: "1 OK CAPABILITY\r\n" Dec 7 11:16:10 mail-proxy perdition[5863]: CLIENT: "3 authenticate NTLM\r\n" Dec 7 11:16:10 mail-proxy perdition[5863]: SELF: "3 NO AUTHENTICATE mechanism not supported, mate\r\n" Is this type of connection not supported at all, or am i missing anything? Note: Not supporting this type of authentication will turn into a major helpdesk overhead since there will be a lot of clients to be reconfigured.
