[Samba] -513 = 100 in tdb mode ?

[Simon FONTENEAU]

Hi

Quick question about something I find surprising:

In tdb mode :

net cache list -s /etc/samba/smb.conf |grep '\-513'
Key: IDMAP/GID2SID/100     Timeout: Tue Apr  9 14:34:48 2024 Value: 
S-1-5-21-1040823229-2152490729-3717368692-513

id of group "domain users" is 100

But id 100 use by "users" system group:

getent group|grep users
users:x:100:

Is this something voluntary?
