When using a SCOPE record the UID and LID need to be specified together:
UID
Specifies the one to 24-character UID or UID mask to be placed in the scope of the logonid. You must also specify a LID entry to permit access to the Logonid database.
LID
Specifies logonids or logonid masks that the scoped logonid can create, list, alter, or delete. You must also specify a UID entry to permit access to records in the Logonid database.
Typically if you specify a UID, you can specify LID(-). You can either add LID(-) or LID(CSI-) and the SCOPE record should work. After making any change to a SCOPE record be sure to issue the 'F ACF2,REBUILD(SCP),CLASS(S)'
