Dear List
I've successfully installed/configured dovecot 1.2.10 with "require client cert" on centos 5.4 and ubuntu server 9.10
I also need to install on centos 4.8 and after the following the exact same procedure I can only get it working if I commented out ssl_require_client_cert =yes and ssl_username_from_cert = yes from the working config file.
This is even after compiling dovecot with openssl 0.9.8l on centos 4.8
If I copy the same "client_ca.crt" from centos 4.8 to centos 5.4 then centos 5.4 does not problem in verifying client cert.
That file contain CRL as well as certificate which signs the pkcs12 file installed on the client.
The following log entries do not appear on centos 5.4

$ dovecot -n
