Created.

Fixed desired _access parm to SamConnect() and SamOpenAlias().
Fixed misleading msg when SamOpenDomain() fails.
Call NetpGetLocalDomainId() instead of NetpGetDomainId() so we can get
the kind that SamOpenDomain() wants.
Only _open aliases for this product type.

RAID 10139: PortUAS should add to admin group/alias.
Fixed PortUasAliasSetup's error handling.
27-Jan-1993 JohnRo
RAID 8683: PortUAS should set primary group from Mac parms.
Use NetLib's get product type function.
