LDAP: error code 53 - Function Not Implemented

[Rahul Sonawale]

Hi All,
While doing search on Oracle internet directory server(oracle ldap server),
we are getting following exception.

Exception in thread "main" javax.naming.OperationNotSupportedException: [LDAP: error code 53 - Function Not Implemented]; remaining name 'ou=people,dc=test,dc=com'
at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3058)

at DifferentSearches.doFilterSearch(DifferentSearches.java:99)
at DifferentSearches.main(DifferentSearches.java:23)


Following is the code -

DirContext ctx=  getDirContext();
SearchControls ctls = new SearchControls();
ctls. setReturningObjFlag (true);
ctls.setSearchScope(SearchControls.SUBTREE_SCOPE);
String filter = "(displayname=chandra)";
NamingEnumeration answer = ctx.search("ou=people,dc=test,dc=com", filter, ctls);
formatResults(answer);
ctx.close();

When we search on the added attributes (like currentsession count) it works fine. For this we had to enable index in OID on this field. But this is not possible for the default attributes. OID does not provide a way to enable indexing on these attributes. Could someone please let us know how we can search on default attributes ?
Regards
Rahul
