[Samba] Problem after update version 4.15.0

[L.P.H. van Belle]

Hai Rowland, 


0xC000006D	The cause is either a bad username or authentication information

"or authentication information" ... 

So, im thinking, these older pc's what used in samba in the low samba version
And the encryptions how its saved maybe.. Like DES/3DES/AES 
Lots of problems i see ( in other forum and mailing lists ) involve encryptions. 

Thinking with an open mind here..
