displayName operational attribute
The attribute displayName, from the inetOrgPerson schema, has been implemented in the Domino® LDAP server to improve performance of name resolution queries from external LDAP servers.
The name for displayName is the user's
abbreviated name. Thus, the displayName value
for cn=John Doe,ou=Anytown,o=Renovations
is John
Doe/Anytown/Renovations.
Domino® serves up displayName from the existing Person.DisplayName field. The latter is already included in the pubnames.ntf design, but its field properties reveal that it is computed for display.
Because the design of displayName is computed for display, it cannot be modified, so RELOADSCHEMA makes the inetOrgPerson displayName a no-user-modification (read-only) attribute.
