Re: Can somebody help me to get schemas from ldap server?

BTW, OpenLDAP 2.x provides an LDAPv3 implementation.

Every entry should have a subschemaSubentry attribute whose value
refers to the subschema entry (or subentry) which controls it.

One must be very careful using the subschemaSubentry attribute
in the root DSE due to the fact that there may be multiple
subschema subentries and the root DSE provides no mechanism
for the client to relate which subentry controls which entry
held by the server.  Client developers should avoid using the
subschemaSubentry within the root DSE as this mechanism is likely
to be changed when LDAPv3 goes from Proposed to Draft Standard.
