ldaps connection

Hi all 

i would like to use mic checking users from ldap  server.

this is what works:

root@serverX-mic0 ~]# cat /etc/ldap.conf
URI ldap://192.168.1.12
BASE ou=domain1,ou=domain2,dc=domain3,dc=org
binddn    cn=micuser,ou=users,ou=domain1,ou=domain2,dc=domain3,dc=org
bindpw    password:)
bind_policy soft

but i need to use ssl or tls. Is it possible?

Next. In ldap database there are only user's public keys not passwords. Could mic use something to authenticate this users?

thanks

Jan
