Here is what I use for supporting most clients I can:

plain_password:
driver = plaintext
public_name = PLAIN
server_condition = ${if crypteq{$3}{${lookup pgsql{select password from
users
where (username || '@' || domain = '$2') or (username = '$2' and domain =
'default.com') }{$value}fail}} {1}}
server_set_id = $2

login_password:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = ${if crypteq{$2}{${lookup pgsql{select password from
users
where (username || '@' || domain = '$1') or (username = '$1' and domain =
'default.com') }{$value}fail}} {1}}
server_set_id = $1

Obviously, replace the SQL with whatever looks up encrypted passwords for
you, and 'default.com' for the fallback domain if the user does not login
with a domain. You can also add logic to support domain logins on Macs with
OE - which truncates '@domain' so I allow '%domain' in another config.

For really simple auth you could hardwire this:

plain_password:
driver = plaintext
public_name = PLAIN
server_condition = ${if crypteq{$3}{YOURENCRYPTEDPASSWORD}}
server_set_id = $2

login_password:
driver = plaintext
public_name = LOGIN
server_prompts = "Username:: : Password::"
server_condition = ${if crypteq{$2}{YOURENCRYPTEDPASSWORD}
server_set_id = $1

server_set_id then just passes on the username...
