We have samba 2.07 loaded to a Sun Solaris 2.6 server. We use "share" as the security level and ask users to provide unix account and user password and it will authenicate. However, users who use the windows 2000 professional through corporate network (NT 4.0 domain) is having problems to map network drives to our samba server. The corporate network personnel suggest us to use "security server" and use their password server. It works great for the windows 2000 users to authenicate through the corporate password server. However, the corporate password server does not recognize our group and its permission in our local nis server. Now users can access their home directories but not able to write to their group directories which the corporate password server do not recognize. Is that a way that we can modify the smb.conf file to accommodate users to authenicate their NT userid with corporate password server in order to access their home directories and authenicate their group file and permission through our local nis server so users can access their group files that we defined in our local nis server. I appreciate any suggestions. Thanks in advance.
