The remote host is missing an update to libpam-ldap announced via advisory DSA 785-1. It has been discovered that libpam-ldap, the Pluggable Authentication Module allowing LDAP interfaces, ignores the result of an attempt to authenticate against an LDAP server that does not set an optional data field. The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in version 178-1sarge1. For the unstable distribution (sid) this problem has been fixed in version 178-1sarge1. We recommend that you upgrade your libpam-ldap package. https://secure1.securityspace.com/smysecure/catid.html?in=DSA%20785-1
