[Samba] SAMBA4 idmap growingwhen using sid-to-uid of not existing SIDs

[Philippe.Simonet at swisscom.com]

Hi samba users

small question : ist that normal that if I query a non-existing SID with wbinfo

wbinfo --sid-to-uid=S-1-5-7777

that an permanent entry is created in idmap.ldb :

ldbsearch -H /var/lib/samba/private/idmap.ldb "(objectSid=S-1-5-7777)"
# record 1
dn: CN=S-1-5-7777
cn: S-1-5-7777
objectClass: sidMap
objectSid: S-1-5-7777
type: ID_TYPE_BOTH
xidNumber: 3000034
distinguishedName: CN=S-1-5-7777

wbinfo -V
Version 4.1.6

thanks and regards
