Hi, i have set up a fileserver with samba 3.5.11-44 from SerNet on a 64Bit centos 5.6. I joined our microsoft domain an everything seems to bee o.k. But when i change a group membership on the AD side, the mapping on the linux side is wrong. For example i have a user "GN" which is member of the group "nwo-ke". Then i and him to "nwo-k" but this doesn't show up on the linux side. [root at file1 NWO-IA]# id gn uid=2273(gn) gid=1513(dom?nen-benutzer) Gruppen=1513(dom?nen-benutzer),2167(nwo-ke) Asking the AD everything is O.K. [root at file1 NWO-IA]# getent group | grep -i nwo-k nwo-ke:x:2167:bb,gn,gt,ha nwo-k:x:2177:he,hj,hu,ik,jj,ma,mr,nb,ro,se,sh,sr,bb,bp,dn,ak,nk,er,ey,gn,go,gr,gt,ha Here is my config: nsswitch.conf .. passwd: files winbind shadow: files winbind group: files winbind .. smb.conf workgroup = NWOINT realm = NWOWHV.INT security = ads template homedir = /home/%U template shell = /bin/bash winbind use default domain = true winbind offline logon = false winbind cache time = 10 winbind nested groups = yes winbind enum users = yes winbind enum groups = yes winbind expand groups = 10 allow trusted domains = yes idmap backend = idmap_rid:NWOINT=1000-20000 idmap uid = 1000-20000 idmap gid = 1000-20000 password server = * Anybody any idea?
