Hi I'm working on Redhat 9.0,and I use Samba 3 alpha 23 as a PDC(not used ldap).I successfully create user and group for domain.I create a share on my windows 2000 workstation(using Server Manager),and I add group permission for the share.It's OK. for example:I have a user trung.h,he belongs to many domain group:domusers,layout,acc (primary group is domusers).And I create a share on my windows 2000 workstation: AW,and grant read permission to group "layout" for the share. -But when I logon to domain with user trung.h,I can't access the share. And when I change the primary group for user trung.h from domusers to layout,and try again,It 's successfull. So,Does the second group in Samba not work or I have made some mistakes.Are there any solutions about it?.Please help me. Thanks in advance __________________________________ Do you Yahoo!? Yahoo!
