[Fedora-directory-users] Binding to Directory Server with Kerberos Tickets

[Hartmann, Tim]

Hi,

I've been configuring our Directory Server implementation to use gss-api
for authentication, and it works great! However I ran into a bit of a
snag and was hoping someone on the list might have a suggestion for a
resolution!

I followed the docs during my configuration and all went well

http://www.redhat.com/docs/manuals/dir-server/ag/8.0/Introduction_to_SASL...

I'm able to bind to our ldap replicas with my TGT when I search the real  hostname,
however we load balance our replicas behind a Cisco SLB which serves out a second hostname
and IP. 

I've updated the ldap keytab file to include both the Kerberos principles for the real
hostname, and the slb hostname, and am still able to sucessfully bind with Kerberos to the
real hostname, but not through the SLB. 

I had a similar problem with kerberized ssh a while back, and the solution there was a
patch to openssh which allowed Kerberos to use any principle in the keytab file. (the
GSSAPIStrictAcceptorCheck flag in ssh provides this)  Does FDS have any similar
configuration option? Or had anyone run into this sort of issue while trying to bind to
ldap via kerberos? 

I'd also be willing to load balance the servers useing some other means beside the
SLB. 

Thanks!!
