 Yes. Other LDAP servers might have a different configuration. Also some

 How can i set DEFAULT password-hash in slapd.conf? such as MD5 or whatever.

That's more a question for the openldap-software mailing list. Since you
already found the password-hash parameter you could simply use it:

password-hash   {SSHA}

Ciao, Michael.

 when creating the SSHA1 hash,

If the password is usable afterwards there's nothing wrong with
client-side password hashing. The salt should be at least 4 bytes long.

 so it would be nice to have
 the directory server do the hashing instead. I've found the
 method:
 
   passwd_s(user, oldpw, newpw, [serverctrls=None, [clientctrls=None]])
 
 but are there any way to use that when I don't know the plaintext
 'oldpw' ?

Simply use None for oldpw.

Ciao, Michael.
