Evening,

I am attempting to get apache authenticating with IPA but not sure why its rejecting the keytab. I have even recreated the keytab a number of times but this isn't making any difference.  To make sure the problem isn't anywhere else, I briefly used a httpasswd file and it worked fine, so confident it has to do with apache IPA integration.  Does anybody notice anything wrong with the setup below?

However, the keytab looks fine.

Also, I have confirmed this isn't selinux related

[root@gitolite4 ~]# getenforce 
Permissive

This is the version of apache module that I am using.
[root@gitolite4 ~]# rpm -qa | grep gssapi
mod_auth_gssapi-1.5.1-5.el7.x86_64
python-gssapi-1.2.0-3.el7.x86_64
cyrus-sasl-gssapi-2.1.26-23.el7.x86_64
[root@gitolite4 ~]# 

This is the configuration that I am using:
<Location /git>
    LimitXMLRequestBody 0
    LimitRequestBody 0
    AuthType GSSAPI
    AuthName "Linux Account"
    GssapiConnectionBound On
    GssapiBasicAuth On
    GssapiNegotiateOnce On
    GssapiLocalName on
    AuthzSendForbiddenOnFailure On
    GssapiCredStore keytab:/etc/httpd/conf.d/httpd.keytab
    GssapiSignalPersistentAuth On
    GssapiSSLonly On
    Require expr %{REMOTE_USER} =~ /@eng.example.com$/
