[Check_mk (english)] multisite auth.secret

I've gone through and checked what the modproxy instructions say and 
still getting an error on the hover popups.

I'm pretty sure I got all the distributed monitoring set up as it should 
be.  Everything else seems to be working at least.

Sockets are set to:

URL prefix:

Multisite URL of remote site:

In /etc/httpd/conf.d/multisite_proxy.conf:
<Location /site1>
         RewriteEngine On
         RewriteRule ^/.+/site1/(.*) http://server1/site1/$1 [P]
<Location /site2>
         RewriteEngine On
         RewriteRule ^/.+/site2/(.*) http://server2/site2/$1 [P]

Both sites and the main server have the same 
/opt/omd/sites/<site>/etc/auth.secret and auth.serials

A filtered list of LDAP users are being pulled from our FreeIPA servers, 
authentication works using that with no issues.  Well one small issue, 
if I start firefox, pull up the main site and login, then try to go to 
the services view for a system on one of the slave servers I have to 
login there also, after that the login is remembered.  I think that's 
the way it normally works but if I can avoid the additional logins to 
slave systems that would be nice. If I could get check_mk to use a 
kerberos TGT for login that would really nice.

I've checked the AuthName in /etc/httpd/conf.d/auth.conf and all three 
systems are the same.

This is the two log entries I see in the slave server apache log when I 
hover over the graph icon from the master site web UI:
<My IP> - - [12/Jul/2016:09:10:02 -0500] "GET 
/sit2/pnp4nagios/index.php/popup?host=host1&srv=_HOST_ HTTP/1.1" 302 - 
"Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:47.0) Gecko/20100101 

<My IP> - - [12/Jul/2016:09:10:02 -0500] "GET 
HTTP/1.1" 200 2202 
"Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:47.0) Gecko/20100101 

I'm probably missing one little step in the setup but I'm having a heck 
of a time finding that one step.
