[Samba] username map and multiple domains

[Michal Toth]

hi all,

i would like to ask how can one specify a domain in username map file. I 
mean that my samba server is member of domain DOM1 (security=domain), 
but there also is another domain DOM2 and a trust relationship exists 
between these two (managed on nt level between pdcs, no idea how). In 
general, i have to allow accounts from DOM1 and DOM2 to access shares on 
this samba server. Is it possible?

thanks and regards
