This boolean controls whether encrypted passwords will be negotiated
with the client. Note that Windows NT 4.0 SP3 and above and also
Windows 98 will by default expect encrypted passwords unless a reg‐
istry entry is changed. To use encrypted passwords in Samba see the
chapter "User Database" in the Samba HOWTO Collection.
MS Windows clients that expect Microsoft encrypted passwords and
that do not have plain text password support enabled will be able to
connect only to a Samba server that has encrypted password support
enabled and for which the user accounts have a valid encrypted pass‐
word. Refer to the smbpasswd command man page for information
regarding the creation of encrypted passwords for user accounts.
The use of plain text passwords is NOT advised as support for this
feature is no longer maintained in Microsoft Windows products. If
you want to use plain text passwords you must set this parameter to
In order for encrypted passwords to work correctly smbd(8) must
either have access to a local smbpasswd(5) file (see the smb‐
passwd(8) program for information on how to set up and maintain this
file), or set the security = [server|domain|ads] parameter which
causes smbd to authenticate against another server.
