be clear-text.
Several solutions:
1. Set "password-hash {SSHA}" in the slapd.conf and change password via LDAP
Modify Extended Operation (RFC 3062).
2. Generate hashed userPassword value at the client side.
3. Use overlay slapo-ppolicy and set ppolicy_hash_cleartext (but read warnings
in man page before).
