GetSchemaDN() public method

Retrieves the Distiguished Name (DN) for the schema advertised in the root DSE of the Directory Server. The DN can be used with the methods fetchSchema and modify to retreive and extend schema definitions. The schema entry is located by reading subschemaSubentry attribute of the root DSE. This is equivalent to calling {@link #getSchemaDN(String) } with the DN parameter as an empty string: getSchemaDN("").
LDAPException This exception occurs if the schema DN /// cannot be retrieved, or if the subschemaSubentry attribute associated /// with the root DSE contains multiple values. /// ///
