This article explains how to query operational attributes with LDAP. The information is from the eDirectory Libraries for C Developer Kit at http://developer.novell.com. See also TID 10070418.
The information contained in the LDAP operational attributes are read-only. Clients cannot modify the attribute values. All of these operational attributes except creatorsName and ModifiersName are available only through LDAP. CreatorsName and modifiersName are available through LDAP and NDAP.
They are not returned in search results unless explicitly requested by name. They can be requested for all entries in an NDS directory.
Here are the operational attributes listed in the developer kit:
- createTimeStamp
- creatorsName
- entryFlags
- federationBoundary
- localEntryID
- modifiersName
- modifyTimeStamp
- structuralObjectClass
- subordinateCount
- subschemaSubentry
Sample Query
Here's a sample query to extract several operational attributes for user Fred:
./ldapsearch -D cn=admin,o=novell -W -b o=novell cn=fred createtimestamp creatorsname entryflags localentryid modifytimestamp version: 2 # # filter: cn=fred # requesting: createtimestamp creatorsname entryflags localentryid modifytimestamp # # fred,teds dn: cn=fred,o=novell creatorsname: CN=admin,O=novell localEntryID: 32847 entryFlags: 0 createTimeStamp: 20020422213635Z modifyTimeStamp: 20020423212816Z # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1
