ServerName and GssapiAcceptorName - mapping possible?

[pakalee]

Is it possible to use a different VirtualHost ServerName and map the auth to a host principal using GssapiAcceptorName?

ServerName usefulsite.example.com
GssapiAcceptorName "[email protected]"

I've tried those stanzas but get GSS ERROR gss_acquire_cred[_from]() failed to get server creds: ... No key table entry found matching "host/myserver.example.com"@). Even though I have in my apache-readable keytab, host/[email protected]. I've also specified a matching default realm in the krb5.conf.

Do you fall in a situation that is not handled here in the GssapiAcceptorName option description?
