i have followed the document 

https://docs.moodle.org/35/en/NTLM_authentication#IIS_6.0

but there are a lot of concerns 

after compiling mod_auth_ntlm_winbind 

i have update my httpd.conf with below 

"<IfModule !mod_auth_ntlm_winbind.c> 

 LoadModule auth_ntlm_winbind_module /usr/lib/apache2/modules/mod_auth_ntlm_winbind.so 

 </IfModule>"

then i have updated smb.conf with the below 

"workgroup = DOMAINNAME 

 password server = * 

 security = domain 

 encrypt passwords = true 

 idmap uid = 10000-20000 

 idmap gid = 10000-20000"

after that i have tried  net join DOMAINNAME -U Administrator

but i got cannot join as standalone machine

and i can see 

n Windows environments you could also try executing the command (as root):

 # net join DOMAINNAME -S DCSERVER -U Administrator

the document is not clear at all in different points 

appreciate any help
