[Samba] smbpasswd trying to add instead of replace attribut

[Beast]

I have some weird error with one of my samba installation.
When modifying samba password using smbpasswd, samba seems trying to add same attribute (instead of delete and add again), pls see the "MOD" from log file (from different domain) :
