Re: [Samba] Unable to add a particular member to group (Samba 4.6.3)

Hello Rowland,

Have you tried deleting a user, re-creating the same user and then try to add him to a group?

I'm convinced that this will point us in the right direction to correct the bug.

This is the case for this user too... Could it be that Samba is
trying to work with the old SID???

It doesn't work with SID.

Are you up to trying something ?

If so, first find a Samba python file 'samdb.py' this is usually in
this directory path 'python2.x/site-packages/samba/'

Backup your original file, then open the original in an editor and find
this line:

ldb.binary_encode(member), ldb.binary_encode(member)), attrs=[])

In my copy it is line 271 under 'def add_remove_group_members(self,
groupname, members,'

Change it to:

member, member), attrs=[])

Make sure the characters start at the same place as they do now.

close and save the file.

Now, try again.
