Even though LockerWrtUser is there to indicate which database user the
management node should use to login to the db, the only value the
daemon will start with is vcl. Has anyone ever gotten the vcld to
start successfully and checkin with the database when using something
other than 'vcl' (specified in vcld.conf as LockerWrtUser)?
Is that clearer?
Best,

Could you re-phrase this part? I don't understand what issue your
highlighting?
The value assigned to 'LockerWrtUser=' is the variable used when
vcld starts to make the database connection.

I've resolved my issue, but I do think there is a bug here. It
seems the
SELECT, INSERT, UPDATE, DELETE permissions are all the management
node's
database user requires. However, even though there is a parameter in
/etc/vcl/vcld.conf for LockerWrtUser, the value the management node
will
check in with is when:
LockerWrtUser=vcl
I am not sure why.

I believe this is default user permissions bug because when I give
my vcl user in the database full permissions (All Privileges)
instead of the recommended in the instructions (SELECT, INSERT,
UPDATE, DELETE), it works. What are the right permissions for a
frontend user? What are the right permissions for a backend user?
Do the instructions need to be updated?

Brian
