openldap openldap-2.2.17 binding problem with crypt

[Tron Fu <tron@soltec.net>]

I have installed openldap-2.2.17 on fedora, configured with 
--enable-crypt. However, whenever I try to bind to slapd with 
ldapsearch (with simple-bind option -x) it fails "ldap_bind: Invalid 
credentials (49)", if the password for the user is stored in crypt 
format but succeeds if the password for the same user is stored as SHA.

What do i need to do to be able to bind as a user with "crypt" 
encrypted password?

thanks,
tron
