[Samba] fix duplicated sambaSID

[basti.mueller31 at web.de]

Hi,
I just want to migrate my Samba PDC (with LDAP backend) to a Active Directory.
On the migration page (https://wiki.samba.org/index.php/Migrating_a_Samba_NT4_Domain_to_Samba_AD_(Classic_Upgrade[https://deref-web-02.de/mail/client/IywWde3X0uo/dereferrer/?redirectUrl=https%3A%2F%2Fwiki.samba.org%2Findex.php%2FMigrating_a_Samba_NT4_Domain_to_Samba_AD_%28Classic_Upgrade])) is a section "Prevent failure due to duplicate SID's".
I executed the script and got the following output:
Duplicate id:  sambaSID: S-1-5-21-3094887387-3947034481-3986156802
How can I fix that?
