Do you have any users on the Linux machine ?
Are these users (if any), members of the group gc55_data2 ?

How do you expect a user that doesn't exist to be a 'valid user' ?

Probably, possibly ???

Well as the 'valid user' doesn't exist, then there isn't a reason for
the line.

On a standalone server, you need to replicate your windows users as
Samba and Unix users on the standalone server. The Samba user must have
the same password as the Windows user, the Unix user doesn't need to
have the same password, but it usually does. To put it another way:
You would need this:
Windows user 'fred' would be the the Unix and Samba user 'fred' on the
Linux machine.
You would also map windows groups to Unix groups with the 'net
groupmap' command, in this case, the group names do not need to match.

What you would be running is a 'WORKGROUP'
