I have upgraded from Samba 3 to Samba 4 for authentication (Windows and Linux 
authentication are working). Samba 4 is acting as the DC. 

However, there are some issues that I can't resolve involving both profiles and 
automatic home folder mapping. 

I have 3 samba servers that are at Samba 3.5 (1 server) and 3.0 (2 servers). 
Prior to the upgrade, both roaming profiles and automatic mapping of home 
folders worked. I was able to join all 3 systems to the new samba 4 AD domain. 
Kerberos is working (I can get tickets via kinit) on all three of the samba 3 
servers. 

For the homes and profiles folders, the section of my smb.conf file is: 

[homes] 
comment = Home Directories 
browseable = yes 
writable = yes 
valid users = %S 
create mask = 0600 
directory mask = 0700 
csc policy = disable 
nt acl support = yes 

[profiles] 
comment = AUTH1 Network Profiles Service 
path = /opt/samba/profiles 
read only = no 
store dos attributes = Yes 
create mask = 0600 
directory mask = 0700 
csc policy = disable 
nt acl support = yes 
hide files = /desktop.ini 

[profiles.V2] 
copy = profiles 
browseable = no 
read only = no 

For the accounts, (in ADUC), a user has the profile path specified as 
\\auth1\profiles\USERNAME and the Home Folder using the Connect option to 
\\fs2\homes\USERNAME where auth1 is the server storing the profiles and fs2 is 
the file server with the users home directory. The filesystem are mounted with 
the acl option. The systems are running Centos5.9. 

I can get the profiles to work by nfs mounting the existing profiles to the new 
samba4 server and specifying the profiles and the samba 4 server via 

[Profiles] 
path = /opt/samba/Profiles 
read only = no 

where I have nfs mounted /opt/samba from auth1 /opt/samba. It is a kludge but 
works for the moment. I can't however get the home folders to map. I can browse 
to them and they are being shared (e.g. if I login as a user, I can browse to 
fs2 and I'll see homes and the username folders shared.) I can even manually 
map the folders. However, I can't change/add permissions as suggested here: 
https://wiki.samba.org/index.php/Samba_%26_Windows_Profiles#Profiles_share_on_a_Samba_4.x_server
 for the samba 3 servers. 

I will be upgrading these servers to Ubuntu 12.04 with Samba 4 but in the 
interim I need to get automatic mappings working if possible. I can use a 
startup script to map the folders if that is the only option as well. 

Sincerely, 
Dave Hopkins
