Config: Reading value from file for password does not work

Hi,

I want to read the ldap auth-dn password from a file to avoid having it as part of the configuration (which may be checked into VCS).

I specified

ldap_auth_dn_password = </some/file

where /some/file contains the password without extra whitespace (esp. there is no \n, I checked with xxd).

But ldap auth does not succeed because of a wrong password. Password itself does work though, as checked with ldapsearch (even using the same file as password provider)

doveconf -x -P *does* show the correct value.

The same issue has been reported back in 2019 [1], without any reply though :-/

Any ideas?

Thanks, René
