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.

Best Regards,

Hugo Monteiro.
