I would second the proposal of setting up an LDAP at our secondary
hosting environment (could we call it that?). It has still not been
worked out how SSO is going to be implemented using OGC interfaces
either. In the long run we will want to have SSO including the Wiki, the
OSGeo domain *and* the OSGeo SDI stack. That would be cool. Maybe add
some GeoACXML certification to the process, reduces the overhead of
logging into LDAPs and reading Cookies across domain limits.
Maybe I have missed it but there was some talk about an infrastructure
workgroup/taskforce/someone for the telescience. Latest information that
I have is that Mark Lucas is the SSO/CVS for this topic and Norman Vine
one of the setup scripts / executables. :-) Correct?
