changing the dn; various breakage.

[Jurgen B. <ju...@bo...>]

So I wrote simple little program to change the dn of an entry
(attached), and first it fails as follows:

  $ perl rename.pl uid=jbotz,ou=people,o=eazel password \
  uid=tuser,ou=people,o=eazel uid=tuser1,ou=people,o=eazel
 
  Can't call method "modify" on an undefined value at
  /usr/lib/perl5/site_perl/5.005/Net/LDAP/Entry.pm line 200

This seems to be because I call $entry->update without any args,
but the manual sez:
  CLIENT is only optional if the Net::LDAP::Entry object was created
  by a search on a directory server. In which case, if omitted, the
  update will be sent back to the same server.

Well, whatever, maybe this doesn't hold for changed dn's so, I give
it an explicit $entry->update($ldap).  Now I get:

  $ perl rename.pl uid=jbotz,ou=people,o=eazel password \
  uid=tuser,ou=people,o=eazel uid=tuser1,ou=people,o=eazel 

  Can't use an undefined value as an ARRAY reference at
  /usr/lib/perl5/site_perl/5.005/Net/LDAP.pm line 313.

This seems to be because Net::LDAP->modify doesn't know its change
type.  Adding an explicit $entry->changetype('modify') to my script
gets me further, but shouldn't the fact that I changed the dn have
tipped it off?

Anyway, now my program runs all the way through and produces the
following error:

   Error: LDAP_PROTOCOL_ERROR -- Unrecognized version number or incorrect
   PDU structure

Right now I'm pretty clueless what this could mean.  All I'm trying 
to do at the moment is change the RDN!  (On a Netscape 4.11 server,
and the OpenLDAP ldapmodrdn(1) program works fine.)
