[Dovecot] Clear-text ldap passwords: {CLEAR} scheme?

[Kristof Bajnok]

Hi,

if I read the documentation correctly, the clear-text password storage
scheme in Dovecot is called PLAIN. Unfortunately, in Sun LDAP Directory
Server I have to specify them as "{CLEAR}" [1].

Is it somehow possible to make Dovecot recognise "{clear}foobar"
passwords as plaintext? Now I get:
  auth: Error: ldap(username): Unknown scheme clear

Thanks,
Kristof
