Custom kdc lookup

[Paul Moore]

I dont know if this is an old topic or not.
I would like to replace the mechanism that kerberos uses for locating
KDCs.
My proposal would be to allow the calling application to do something
along these lines
 
krb5_set_locator(<context, <my locator function>);
 
This function sets a callback pointer in the context block
And then have krb5_locate_kdc look to see of this function pointer is
non null and if so call <my function> instead of the standard sequence.
Of course I could simply hack this into the code base but would much
prefer to have it in the main code line. It seems that this could be
useful for
many people with non standard kdc discovery processes.
