dynamic schema update

[Justin <da...@io...>]

Greetings!

I am now trying to write a modified schema entry back to the directory
and am having problems.  Perhaps someone here can see the error of my ways.
This is how I'm trying to do it:

  Create a Net::LDAP::Entry, $entry
  Set the $entry->dn("cn=Schema");
  Create a multivalued hash with keys "attributetypes" and "objectclasses"
  Call $entry->modify() with "replace" and the reference to the above hash.

  This call returns: 0x35 LDAP_MOD_REPLACE is not implemented on schema entry


What I'm wondering is:

 -Is this error coming from the perl ldap modules?

 -Is modify/replace the proper way to programmatically affect the directory
  schema?


Thanks for your suggestions.
 Justin

What LDAP server implementation are you using?

I suppose that it's possible that the server implementation doesn't
support modifying schema on the fly.

I knew I forgot something :)

I'm using Netscape Directory Server 4.12 with Perl-ldap 0.22

I believe the error message is telling you the dynamic schema modifications are
not allowed
(implemented) on your server.

Many directory servers do not allow dynamic schema modifications, you have to
modify the
schema control files and then restart the directory server.

It would help to know what company provided the directory server.

Given the error message mentions LDAP_MOD_REPLACE,
you might try modify/add-values instead of
modify/replace-values.  Of course, as others have
pointed out, the server might not support any
modification of a subschema entry (or subentry)
via LDAP.  I note that subschema modification is
an elective feature of LDAPv3.
