I've installed camail 0.2.1 but when I try to login through ../cgi-bin/camail/camail.pl that is what happens:

Error Message:      The user is not allowed to use CaMail
Error Parameters:      LDAP suffix : o=sessions

I've used the slapd.conf provided in the package and I'm running openldap-2.0.9. I've checked the configuration for my network and it is correct.

What might be the problem?
