Metacat

Metacat currently retrieves a userid from the client, and uses this along with a
single configuarable baseDN parameter to determine the string that is used to
look up the user in LDAP, and ultimately to authenticate them. This will not
work if we have LDAP configured to refer some authentication to alternate
servers (like the LTER personell db). In the new scheme, metacat MUST get the
complete DN from the client, so that it can be passed to the correct LDAP server
for authentication.

So, instead of passing:
jones
Morpho must pass:
uid=jones,o=NCEAS,dc=ecoinformatics,dc=org
in order for metacat to use referral properly.
