[Samba] samba winbind error "host is not configured as a member server"

[kartheek katakam]

hello,

I had weird issues that I am running into.
1. I have manually updated "security = ads" entry in /etc/samba/smb.conf
but when I run testparm on the samba configuration file I didnot notice
this security line,its not just one line and I have noticed few other lines
missing, sure what going on !!!

[root at LinuxADtest samba]# testparm /etc/samba/smb.conf
Load smb config files from /etc/samba/smb.conf
Loaded services file OK.
'winbind separator = +' might cause problems with group membership.

Host is not configured as a member server.

Invalid configuration.  Exiting....

Failed to join domain: This operation is only allowed for the PDC of the
