According to Samba official HOWTO, plaintext is a password backend:
http://us1.samba.org/samba/docs/man/Samba-HOWTO-Collection/passdb.html
grep "user information" - you'll see "Plaintext" heading listed under
the heading "Password Backends".

Also the table of contents implies that "Plaintext" is a "Password
Backend" (from the same URL):

Password Backends 
		Plaintext 
		smbpasswd Encrypted Password Database
		tdbsam
		ldapsam
		MySQL
		XML
