Can you try this: # openssl s_client -host lnxrealmtest01.liberty.edu -port 443 -CAfile /etc/ipa/ca.crt Adding the -debug flag will add even more output. rob [klarmstrong2@r6-idmclient<mailto:klarmstrong2@r6-idmclient> ~]$ sudo openssl s_client -host lnxrealmtest01.liberty.edu -port 443 -CAfile /etc/ipa/ca.crt [sudo] password for klarmstrong2: CONNECTED(00000003) depth=0 O = LNXREALMTEST.LIBERTY.EDU, CN = lnxrealmtest01.liberty.edu verify error:num=20:unable to get local issuer certificate verify return:1 depth=0 O = LNXREALMTEST.LIBERTY.EDU, CN = lnxrealmtest01.liberty.edu verify error:num=27:certificate not trusted verify return:1 depth=0 O = LNXREALMTEST.LIBERTY.EDU, CN = lnxrealmtest01.liberty.edu verify error:num=21:unable to verify the first certificate verify return:1 --- Certificate chain 0 s:/O=LNXREALMTEST.LIBERTY.EDU/CN=lnxrealmtest01.liberty.edu i:/O=LNXREALMTEST.LIBERTY.EDU/CN=Certificate Authority 1 s:/O=LNXREALMTEST.LIBERTY.EDU/CN=Certificate Authority i:/DC=edu/DC=liberty/CN=LUPKI01 --- Server certificate -----BEGIN CERTIFICATE----- ... -----END CERTIFICATE----- subject=/O=LNXREALMTEST.LIBERTY.EDU/CN=lnxrealmtest01.liberty.edu issuer=/O=LNXREALMTEST.LIBERTY.EDU/CN=Certificate Authority --- No client certificate CA names sent --- SSL handshake has read 2629 bytes and written 462 bytes --- New, TLSv1/SSLv3, Cipher is AES256-SHA Server public key is 2048 bit Secure Renegotiation IS supported Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : AES256-SHA Session-ID: 0D52FB7937A013C4F0F26E77B24A6133DB3B6D760BD1C65F0010A326A195FDEE Session-ID-ctx: Master-Key: ...
