RE: GASH schema changes proposed for dev3

["King, Curtis" <curtis.king@cul.ca>]

It really doesn't make a difference to me if Ganymede becomes a
replacement for GASH or supersede it.  Well, I do prefer if it would
meet today's requirements for DNS, LDAP, etc even if you sacrifice
compatibility with GASH.  What is really important to me with Ganymede
is that maintains a Meta-Directory status of being a central store for
all information for all directory services.  This is the biggest benefit
of Ganymede, one tool to maintain, teach, etc.  If it means to sacrifice
Ganymede as a Meta-Directory to give GASH compatibility by having to add
a separate schema support more complex DNS.  I would vote to make a
whole new schema.
