finder – Samba shared between MacOS 11.3 and Debian 10 : password incorrect

On Big Sur 11.3 Big Sur, I do a CMD+K in Finder to connect to my Debian 10 Samba server named “pablo”:example

But impossible to enter the right password, I am systematically rejected by the password.

My login is : fab

I tried with password of MacOS 11.3 Big Sur and with password of Debian 10 but none of two works.

I edited the config file of SAMBA on Debian SAMBA server but there is not password is indicated.

Anyone has already had this kind of problem ?

I don’t know what to do more.
