I am trying to get Dovecot IMAP and Outlook to talk to each other with SSL and client certificates enabled. In Dovecot, I have the following options enabled:

 

ssl_ca = ...

ssl_verify_client_cert = yes

auth_ssl_require_client_cert = yes

auth_ssl_username_from_cert = yes

 

when I try to connect with Outlook, I get:

 

May 12 08:07:50 mail dovecot: imap-login: Disconnected (client didn't send a cert): user=<>, method=PLAIN, rip=192.168.1.245, lip=192.168.2.5, TLS: Disconnected, session=<is7gpa+Im97AqAH1>

 

But when I use openssl directly with the same certificates it seems to pass the certificate in just fine. Does anybody have any ideas?

 

Thanks in advance.

 

Maybe Outlook is misconfigured? Does it ask for a certificate when you connect?
