samba pdc mapping windows groups to unix groups

Dear Sir/Madam:

configured the linux as domain controller  
[root@parrot ~]# net groupmap list
Domain Admins (S-1-5-21-386657565-2353459576-620808375-512) -> 533
Domain Users (S-1-5-21-386657565-2353459576-620808375-513) -> users
Domain Guests (S-1-5-21-386657565-2353459576-620808375-514) -> nobody

created unix groups : ntadmins , users and nobody

when tried to map them to windows groups with the following command getting the error :

[root@parrot ~]# groupadd ntadmins
groupadd: group ntadmins exists
[root@parrot ~]# net groupmap modify ntgroup="Domain Admins"unixgroup=ntadmins
NT Group Domain Adminsunixgroup=ntadmins doesn't exist in mapping DB

please help me on this.

Hi,

You need to use "net groupmap" command to map groups.

This is the usage of the command:
net groupmap add rid=1000 ntgroup="Accounting" unixgroup=acct type=d

Please note the type=d switch it means that the gorup is a domain group.

For mote informaion please browse here:

thanks sir did accordingly could able to map users  and when root login roaming profile is loaded from the linux domain controller but for ordinary samba users following message appears in the windows:

Windows did not load your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. Windows did not load your profile because a server copy of the profile folder already exists that does not have the correct security. Either the current user or the Administrator's group must be the owner of the folder. Contact your network administrator.

ok so in fact the answer to your question is ok. now you are asking another question. Let me remind you that it is better to close the question and pen-up another one is the best method for people to reach answer. Anyway the answer to your new question is that: Policies require that profiles be owned by the logged in user by defalt to prevent this follow these steps:

   - Run Group Policy editor (gpedit.msc)
   - Select Computer Configuration > Administrative Templates >  System > User Profiles
   - Remove check for user ownership of Roaming Profile Folders (Enabled)

If the key is not already there you can create it too:
    [HKEY_LOCAL_MACHINE \ SOFTWARE \ Policies \ Microsoft \ Windows \ System]:            CompatibleRUPSecurity = dword:00000001
