You are doing this in production aren't you, did you not do any testing
before putting it into production ?

In answer to your question, winbind uses the smb.conf file, but yours
was not set up correctly for winbind.

Try reading this:


I repeat, you cannot use winbind with sssd installed, they both have a
version of a winbind lib, you need to choose one or the other.

If you must use the user '16777216' then change the '10000-999999'
range to reflect this.
