I was able to get my windows domain authentication working to enable single sign on for a wiki we recently deployed on a CentOS server. I understand the wiki is capable of supporting single sign on for multiple windows domains with a few configuration changes and have made those changes. My question however revolves around my /etc/samba/smb.conf file which I had to edit to get winbind working correctly in order to do all of this. My smb.conf contains specific information obviously about the domain such as: workgroup = domainname1 security = domain password server = pdc.domainname1.someplace.com bdc.domainname1.someplace.com idmap uid = 10000-20000 idmap gid = 10000-20000 winbind use default domain = yes I suspect one of two things has to happen. I have edit my existing smb.conf and add the new info or create a new smb.conf that will possibly be used by a second instance of winbind? I say that because I question whether you could do something like: workgroup = domainname1 workgroup = domainname2 security = domain password server = pdc.domainname1.someplace.com bdc.domainname1.someplace.com password server = pdc.domainname2.someplace.com bdc.domainname2.someplace.com idmap uid = 10000-20000 idmap gid = 10000-20000 winbind use default domain = yes I would think you would have to some how tie the new workgroup to the right password server/s. Am I off base here? Can anyone get me guided in the right direction? Thanks, Dane
