Cause:
Previously wget was missing support for Server Name Indication (SNI).
Consequence:

Fix:
The SNI support has been ported to the wget distributed in RHEL-6.
Result:
As a result, wget is now able to successfully validate certificate from server that uses SNI, if the certificate is valid.

(In reply to comment #0) > wget-1.12-1.4.el6 contains no support for SNI (Server Name Indication): > > [root@tools01 hooks]# wget --ca-certificate=... --certificate=... > https://ci.example.org > --2013-02-09 19:09:23-- https://ci.example.org/ > Resolving ci.example.org... 217.72.x.x, 217.72.x.x > Connecting to ci.example.org|217.72.x.x|:443... connected. > ERROR: certificate common name `svn.example.org' doesn't match requested > host name `ci.example.org'. However this is true, your problem might be caused by something else. wget-1.12-1.4.el6 does NOT support subjectAltName field in certificates introduced in X.509v3 specification. (Bug #736445) I will leave this Bug open so it can get fixed in the future. Created attachment 696067 [details]
Patch for TLS SNI issue
This particular bug is an SNI bug, and has nothing to do with subjectAltName. The svn.example.org cert (obviously not it's real name) is a domain validated cert from Thawte, which contains no subjectAltName entries. (In reply to comment #4) > This particular bug is an SNI bug, and has nothing to do with subjectAltName. I did NOT see the certificate your wget is getting therefore I just stated there might be also another reason why you are getting this error. >The svn.example.org cert (obviously not it's real name) is a > domain validated cert from Thawte, which contains no subjectAltName entries. Then this is for sure SNI related bug. Thank you for clarification. Just to clarify, the bug was raised after an analysis determined SNI not be working, it wasn't a request for support. Switching wget away and replacing it with curl (which does support SNI) worked around our specific problem for now. This request was evaluated by Red Hat Product Management for inclusion in the current release of Red Hat Enterprise Linux. Because the affected component is not scheduled to be updated in the current release, Red Hat is unable to address this request at this time. Red Hat invites you to ask your support representative to propose this request, if appropriate, in the next release of Red Hat Enterprise Linux. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
