Access authorization

[Nadine Anderson Hunt]

Hi all
I am using samba ver 1.9.16p11 and we
disengaged all the shares in the smb.conf
and only allow the system admin personnel to
uncomment shares as they wish (security
reasons) however, the biggest problem that we
are having is that we are unable to access
samba at all, it shows up on the computer but
he shares that are uncommented cannot be
accessed with valid UNIX login and passwords.
Can anyone help
Thanks
