Re: [Dovecot] SSL cert problems.
Ok, how about from a little different approach. How do I get debugging out of this thing? I followed this: http://wiki.dovecot.org/Logging But I certainly don't consider what it produced in the way of output something I could consider "debug" logging. It never even once logged anything like directories it was looking in for SSL stuff, or acknowledged my connection with more then "TLS" in the connection line. How do I get more logging out? -G On Mon, 2008-12-29 at 16:54 -0500, Sahil Tandon wrote: > Egbert Jan van den Bussche wrote: > > > Still strange that Verisign is not already in your cert. store.

Re: [Dovecot] SSL cert problems.
Still strange that Verisign is not already in your cert. store. Most browsers seem to have Verisign. I'm used to the fact that my CA (Cacert) is not included, being a small free CA. I often have to import class3 and root cert. which is not a big deal after all. Only thing I can say about your problem is that the ---BEGIN CERTIFICATE--- line should be on a line by its own. It is a far shot but maybe it helps. We are dealing with security stuff and all files (and permissions!) are very strict. Your key file should be on 600.

Re: [Dovecot] SSL cert problems.
Ok so I downloaded the intermediate ca cert thing onto my local machine as intca.cer. Then I ran this command: :~$ openssl s_client -ssl3 -CApath ./intca.cer -connect pop.x10.com:995 CONNECTED(0003) depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=27:certificate not trusted verify return:1 depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=21:unable to verify the first certificate verify return:1 --- Certificate chain 0 s:/C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com i:/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)05/CN=VeriSign Class 3 Secure Server CA --- Server certificate -BEGIN CERTIFICATE- MIIFVDCCBDygAwIBAgIQP9qDpsFNkAq3EZsq5A0jTjANBgkqhkiG9w0BAQUFADCB sDELMAkGA1UEBhMCVVMxFzAVBgNVBAoTDlZlcmlTaWduLCBJbmMuMR8wHQYDVQQL ExZWZXJpU2lnbiBUcnVzdCBOZXR3b3JrMTswOQYDVQQLEzJUZXJtcyBvZiB1c2Ug YXQgaHR0cHM6Ly93d3cudmVyaXNpZ24uY29tL3JwYSAoYykwNTEqMCgGA1UEAxMh VmVyaVNpZ24gQ2xhc3MgMyBTZWN1cmUgU2VydmVyIENBMB4XDTA4MTIxMTAwMDAw MFoXDTA5MTIxMTIzNTk1OVowgccxCzAJBgNVBAYTAlVTMRMwEQYDVQQIEwpXYXNo aW5ndG9uMQ8wDQYDVQQHFAZSZW50b24xJjAkBgNVBAoUHVgxMCBXaXJlbGVzcyBU ZWNobm9sb2d5LCBJbmMuMR8wHQYDVQQLFBZJbmZvcm1hdGlvbiBUZWNobm9sb2d5 MTMwMQYDVQQLFCpUZXJtcyBvZiB1c2UgYXQgd3d3LnZlcmlzaWduLmNvbS9ycGEg KGMpMDUxFDASBgNVBAMUC3BvcC54MTAuY29tMIGfMA0GCSqGSIb3DQEBAQUAA4GN ADCBiQKBgQDJGXMMLkbyNDIVzNv4IB00qqEp8Pg5f2zWU8uzL52w37JHLmAzfExu HU+6vQqMip65QEEefqRh9rrsKWzMHC3ecQ1H3Ca6CDxwSbGLk1FjWafDLK2Ms1+w chOkym9RvURMGn8IKQag1KQ8mZtPGM5z+50O6A6YHaLQUNVGW1mJ8wIDAQABo4IB 0zCCAc8wCQYDVR0TBAIwADALBgNVHQ8EBAMCBaAwRAYDVR0fBD0wOzA5oDegNYYz aHR0cDovL1NWUlNlY3VyZS1jcmwudmVyaXNpZ24uY29tL1NWUlNlY3VyZTIwMDUu Y3JsMEQGA1UdIAQ9MDswOQYLYIZIAYb4RQEHFwMwKjAoBggrBgEFBQcCARYcaHR0 cHM6Ly93d3cudmVyaXNpZ24uY29tL3JwYTAdBgNVHSUEFjAUBggrBgEFBQcDAQYI KwYBBQUHAwIwHwYDVR0jBBgwFoAUb+yvoN2KpO/1KhBnLT9VgrzX7yUweQYIKwYB BQUHAQEEbTBrMCQGCCsGAQUFBzABhhhodHRwOi8vb2NzcC52ZXJpc2lnbi5jb20w QwYIKwYBBQUHMAKGN2h0dHA6Ly9TVlJTZWN1cmUtYWlhLnZlcmlzaWduLmNvbS9T VlJTZWN1cmUyMDA1LWFpYS5jZXIwbgYIKwYBBQUHAQwEYjBgoV6gXDBaMFgwVhYJ aW1hZ2UvZ2lmMCEwHzAHBgUrDgMCGgQUS2u5KJYGDLvQUjibKaxLB4shBRgwJhYk aHR0cDovL2xvZ28udmVyaXNpZ24uY29tL3ZzbG9nbzEuZ2lmMA0GCSqGSIb3DQEB BQUAA4IBAQA70R4JDVgQF7Rz/l26G0smMR2qjj3iOfggXOiE1zHVtyzWb/Q2yrIV kTkC558w73rE0/ScqFKa2HDHm3d6OHWXNRgr+2MW8rtuwFPaPko6mYkWeRE4a3HP VFE2iNOYfx5n5yovQOUbKOKn9jBnJu8L7+mVjmtdLTMLo6yKynrxCMOXrmHI4AkK QZgySYbm4JqkTz8+CPnT75bXAJdsFmqMiq3wTKDI2GbEGdCLEupCEEMcDi2mb/zA UQbon3cgfDGfkCKd91SzJT86c1IGStHNiuwgOHsM/cAmTobICdBeooBBGQlGZPZ1 E6ehkR3x1HVzD53zpE/rH4ejjhHZ3I02 -END CERTIFICATE- subject=/C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com issuer=/C=US/O=VeriSign, Inc./OU=VeriSign Trust Network/OU=Terms of use at https://www.verisign.com/rpa (c)05/CN=VeriSign Class 3 Secure Server CA --- No client certificate CA names sent --- SSL handshake has read 1964 bytes and written 317 bytes --- New, TLSv1/SSLv3, Cipher is DHE-RSA-AES256-SHA Server public key is 1024 bit Compression: zlib compression Expansion: zlib compression SSL-Session: Protocol : SSLv3 Cipher: DHE-RSA-AES256-SHA Session-ID: F5FDC92F3DFEE11EABFECEF9ACAEA69F6E34B18A0DAEC225EE6C18398E86B418 Session-ID-ctx: Master-Key: E81D48B88F493F4BD35353079B7A596993D42C3E711F2E4DB79305E69C9D0CF97ED4A88941FE42B3BE012A3D507827C8 Key-Arg : None Compression: 1 (zlib compression) Start Time: 1230103587 Timeout : 7200 (sec) Verify return code: 21 (unable to verify the first certificate) --- +OK Dovecot ready.

The same test will fail even with gmail's IMAP and POP3 servers. See the s_client(1) man page for the CApath and CAfile flags. -- Sahil Tandon
[Dovecot] SSL cert problems.
I'm really racking my brain trying to figure this one out here. I am running a pop3 server for remote offices on CentOS 5.2. We purchased a SSL cert from Verisign and installed it on our dovecot server, but I continue to get failure problems with the cert and I don't know where to go from here. here is some info about our config: dovecot version: # dovecot --version 1.0.7 hostname: pop.x10.com dovecot.conf: # dovecot -n # 1.0.7: /etc/dovecot.conf base_dir: /var/run/dovecot/ log_path: /var/log/dovecot.log protocols: pop3 pop3s ssl_ca_file: /etc/pki/verisign/intermediate_ca.cer ssl_cert_file: /etc/pki/dovecot/certs/pop.x10.com.cer ssl_key_file: /etc/pki/dovecot/private/pop.x10.com.key ssl_cipher_list: HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3 verbose_ssl: yes login_dir: /var/run/dovecot//login login_executable: /usr/libexec/dovecot/pop3-login mail_executable: /usr/libexec/dovecot/pop3 mail_plugin_dir: /usr/lib/dovecot/pop3 pop3_client_workarounds: outlook-no-nuls auth default: passdb: driver: pam userdb: driver: passwd and last but not least, here is my test from openssl. Mind you this fails as a "BAD" ssl cert in Evolution. :~$ openssl s_client -ssl2 -connect pop.x10.com:995 CONNECTED(0003) depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=27:certificate not trusted verify return:1 depth=0 /C=US/ST=Washington/L=Renton/O=X10 Wireless Technology, Inc./OU=Information Technology/OU=Terms of use at www.verisign.com/rpa (c)05/CN=pop.x10.com verify error:num=21:unable to verify the first certificate verify return:1 21568:error:1406D0B8:SSL routines:GET_SERVER_HELLO:no cipher list:s2_clnt.c:450: As you can see, the certificate clearly fails. I don't know how to make this work at this point. Any thoughts or advice would be greatly appreciated. -G
