APAR status

Closed as program error.

Error description

Virtual member manager (VMM) will not return current member
results for an application group if a previous member user has
been deleted from the LDAP. Instead it returns:

com.ibm.websphere.wim.exception.EntityNotFoundException:
CWWIM4527E The
LDAP entry 'uid=user1,ou=users,dc=ibm,dc=com'
was not
found: 'javax.naming.NameNotFoundException: [LDAP: error code 32
- No
Such Object]; remaining name
'uid=user1,ou=users,dc=ibm,dc=com'; resolved
object
com.sun.jndi.ldap.LdapCtx@85f085f'.

Local fix

-Backup VMM database
-The problem can be resolved by deleting the member entry from
DBGRPREL
table using the SQL statement you mentioned below.
 Delete from <dbname>.DBGRPREL where GRP_ID=79 and
EXT_ID='uid=user1,ou=users,dc=ibm,dc=com';
  (GRP_ID 79 is for cn=appGroup1,o=dbRep) )

VMM will not return current member results for an application
group if a previous member user has been deleted from the LDAP.
Instead it returns:
com.ibm.websphere.wim.exception.EntityNotFoundException

Problem conclusion

VMM logic has been updated to show up the remaining
members rather than throwing EntityNotFoundException
by deleting the groupmembership of non existing members only
if user has defined custom property as
"repositoriesForMemberDeletion" and its value will be
";" separated list of repositoryIDs of which user wants to
delete the groupmembership of non existing member.

Details for applying this fix are as follows:

1) define as custom property for the DB repository where Group
resides using following CLI command.
example:
"wsadmin>$AdminTask setIdMgrCustomProperty { -id "DB2Repos"
-name "repositoriesForMemberDeletion" -value "TDS;AD" }"

where

id:-  DB repoId (where group resides)

name:-  this is the custom property name
("repositoriesForMemberDeletion") that VMM will look for
deleting the nonexistent members from group membership.
NOTE:- please do not change the name of this property.

value:- this is the set of Repositories ID (where group member
resides initially) separated via delimiter ";" for which client
wants to delete the membership from group in DB.

NOTE:- If the value of the property is set as "*" then
all non existing members will be removed from the group
membership of application group.
2) restart the server.



The fix for this APAR is currently targeted for inclusion in
fix packs 6.1.0.39 and 7.0.0.17.  Please refer to the
