First off, here is my smb.conf file:
# Samba config file created using SWAT

# Global parameters

 domain groups = adm
 domain admin group = adm
 domain admin users = gerrym, root, cliffb, delphias
 admin users = root, cliffb, gerrym, delphias, patricef

[confid]
 path = /fmit/confid
 valid users = root, cliffb, gerrym, delphias, patricef
 write list = root, cliffb, gerrym, delphias, patricef
 force group = @IT
 read only = No
 create mask = 0770
 directory mask = 0770



[commodore]
 path = /home/samba/commodore
 valid users = @sales, @IT
 write list = @sales, @IT
 force user = @sales
 force group = @sales

[creditx]

[Disk_Img]

[iso9000]

Ok, heres my sys parameters: RH60 running Samba 2.0.5a. I have the
following groups in /etc/groups IT, sales, intsales,credit
all the proper names were added to their corresponding groups.
Problem #1) User johno cannot access the shares iso9000 or iso-9000,
even though I have hime set up as a valid user.
Problem #2) No one, except IT can access scratch, docs, TRImages or
TRData, and I didnt specify any valid users so they
                    could read the files there.
Problem #3) If I remove
                    domain groups = adm
                     domain admin group = adm
                     domain admin users = gerrym, root, cliffb, delphias

                      admin users = root, cliffb, gerrym, delphias,
patricef

                        from the globals section, I cannot even access
this section.
