I have installed Samba-3.0.10 on a Red Hat 9.0 server. I have upgraded my kernel to 2.6.10 in order to support POSIX ACLs (see snippet from my .config file). The server is acting as a primary domain controller. I have added Windows 2000 and XP machines to the domain successfully. I can use User Manager for Domains, sort of. I have added users and groups. I can log in with domain user accounts. However, it seems that a user can only belong to one global group at a time. Why is this? Anyone else have this problem? .config snippet: # File systems CONFIG_EXT3_FS=y CONFIG_EXT3_FS_XATTR=y CONFIG_EXT3_FS_POSIX_ACL=y CONFIG_EXT3_FS_SECURITY=y Regards, Al Miller
