The LDAP driver works with most LDAP v3 compatible LDAP servers. The driver is written to the LDAP specification (IETF RFCs 4510-4519). To increase compatibility with some LDAP servers that don’t fully meet the RFC 2251 requirements, we have added workarounds to the LDAP driver.
One compatibility issue that cannot be ignored or worked around is the RFC 4511 section 4.1.1 requirement that servers allow Message ID values up to 2,147,483,647 (integer values using four bytes).
Oracle Internet Directory version 2.1.1.0.0 (which is part of Oracle 8i) allows only Message ID values up to 32,767 (integer values using two bytes). Therefore, it can’t function properly with the LDAP driver.
If you need compatibility with Oracle Internet Directory, Novell recommends upgrading to version 9.2.0.1.0 (included with Oracle 9i) or later.
