Details

Andrea Barisani discovered a flaw in the SSL handling of pam-ldap and
libnss-ldap. When a client connected to a consumer LDAP server using SSL,
the consumer server did not use SSL as well when contacting the LDAP
provider server. This caused passwords and other confident information
to be transmitted unencrypted between the consumer and the provider.
