When performing an Administrator Driven Batch Migration, the following error may be seen in the logs:
12:00:00 ERROR: [7436-1-97-00000000] Unable to merge 'CN=FirstNameLastName,OU=GroupWise Users,DC=demo,DC=wingra,DC=com'
12:00:00 Security object not found using '(sAMAccountName=FirstName)'.
This error will be received when the "NDSUsername" column value (for the specific user) in the 'UsersToMerge.CSV' does not match existing Active Directory (target) user(s) sAMAccountName value.
Please modify the "NDSUsername" column value in the 'UsersToMerge.CSV' so that it matches the existing Active Directory (target) user(s) sAMAccountName value.
