In LDAP only the short forms are used in protocol.
For LDAPv2, look at sections 4.1 and 4.2 of
draft-ietf-asid-ldapv2-attributes-00.txt.
For LDAPv3, sections 5.1.1 through 5.1.5 of
draft-ietf-asid-ldapv3-attributes-03.txt.
These documents should be available from Internet Draft repositories such as
ftp.ietf.org
Hope this helps,
