Adding A Uniquemember To An Empty Group In OID 10g Fails With Error: One or more values for attribute uniquemember does not exist / Or: "invalid attribute" error (Doc ID 1285654.1)

Last updated on AUGUST 08, 2022

Applies to:

Oracle Internet Directory - Version 9.0.4 to [Release 10gR1 to 10gR3]
Information in this document applies to any platform.


Trying to modify an Oracle Internet Directory (OID) 10g group entry to replace a uniquemember via dbms_ldap fails with:

An error was encountered - -31202 -ERROR- ORA-31202: DBMS_LDAP: LDAP client/server error: No such attribute. One or more values for attribute uniquemember does not exist

Trying via a third party ldap tool (such as LDAP Browser) fails with:

Failed to update entry cn=my_entry, cn=My_Group, cn=Groups, dc=mycompany,dc=com
Root error: [LDAP: error code 16 - One or more values for attribute uniquemember does not exist]

Trying via ldif file and ldapmodify commands fails with:

ldap_modify: No such attribute
ldap_modify: additional info: One or more values for attribute uniquemember does not exist

A different 3rd party tool (such as Tibco for example) may fail with:

"invalid attribute" error

The same code and tools work if first manually adding a uniquemember to the group, i.e., via Oracle Directory Manager (ODM / oidadmin) or via ldif file and ldapmodify, so that the group already contains at least one uniquemember beforehand.

Additional diagnosis:
Turning on level 1 or higher debug in OID as per <Note:397821.1> may then show the following for the failed attempt:

15:10:33 * Replacing cn in gslsbmApplyModtoEntry()
15:10:33 * INFO : gsleswrASndResult2 RESULT = 16 nentries=0

The value after RESULT = is an LDAP error code. In this case the value returned is 16, which means:

Attribute does not exist in the entry specified in the request.

Note:  Details about the standard LDAP error codes returned by OID Server are available in the following documentation:
