> I have Apache httpd 2.2.27 + mod_auth_kerb-5.4 on a RHEL 6 host and

> like to use subversion on the Solaris hosts to authenticate against
> the Kerberos server on the RHEL 6 host. I built serf to link against
> GSSAPI on Solaris (so -DSERF_HAVE_GSSAPI was defined when building
> serf and serf is linked against -ssl). Subversion appears to be
