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

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
