multiple valued workgroup definition

[ics_pto]

Could anyone point to me where is the source code that reads and processes the
workgroup parameter when process the smb.conf file?   It seems to me that samba
accepts multi-value workgroup assignment but Windows doesn't.  For example if I
have the following entry in my smb.conf:

workgroup = group1, group2, group3

What will it be perceived by a samba server?


Also, can anyone point to me a good document source on samba internals, i.e.
explanations of the source code.

Thanks in advance.
