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

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
