Description David Jaša 2014-09-26 10:22:25 UTC

Description of problem:
When accessing some page (one of the Hosts), I keep getting the error 907:
"""
cannot connect to 'https://idm.spice.brq.redhat.com:443/ca/agent/ca/displayBySerial': [Errno -12190] (SSL_ERROR_PROTOCOL_VERSION_ALERT) Peer reports incompatible or unsupported protocol version.
"""
The error started popping up after I disabled TLSv1 in mod_nss configuration. As TLS 1.0 is outdated for quite a long time already, FreeIPA should be able to work in 1.1+1.2 or pure TLS 1.2 environments

Version-Release number of selected component (if applicable):
ipa-server-3.0.0-37.el6.x86_64

How reproducible:
always

Steps to Reproduce:
1. in /etc/httpd/conf.d/nss.conf, change NSSProtocol line to:
NSSProtocol TLSv1.1,TLSv1.2
2. restart httpd
3. browse web ui, try doing some actions

Actual results:
error 907 such as above pops up from time to time

Expected results:
IPA should work without any glitch when only recent TLS versions are enabled in httpd

Additional info:
logs may reveal another pain points...

More specifics are needed on exactly which pages work and which pages do not.

This particular error is associated with fetching data from dogtag to display the certificate status (revoked or not) so it may be that only those entries with certificates are at issue.

Did you test with the cli at all?

I've only seen the error on the host list. My IPA isn't populated enough IMO to see if this is the only occurence of the error or not.

No, I use CLI only seldom so I reported the bug and reverted the setting back.

IPA Poodle fixes are tracked in Bug 1154687, closing this one as duplicate.

If you are interested in TLS 1.2 support in mod_nss, please track Bug 1166316 instead.
