Hi Samba list, I have a Linux Samba PDC file server with a separate ldap machine backend. Every thing works perfect. but the problem is that when I do a command on the samba server: # getent group | grep 1033 It gives me: gname:x:1033:usr1,usr2,usr1,usr2,usr3 Some of the user ids show up twice. Why? I checked ldap database and found that usr1,usr2 and usr3 show up only once in memberUid. All of them do not exist in /etc/passwd and /etc/group files. Software used: RedHat ES v4 2.6.9-5.ELsmp Samba 3.0.22 My nsswitch.conf on samba server looks like: passwd: files ldap shadow: files ldap group: files ldap hosts: files dns bootparams: nisplus [NOTFOUND=return] files ethers: files netmasks: files networks: files protocols: files ldap rpc: files services: files ldap netgroup: files ldap publickey: nisplus automount: files ldap aliases: files nisplus
