Re: (ITS#3632) 2 buggy getpeername calls in client library will result in crash of clients

First, this should not be marked as a major security issue
(see notes on submission page).  I have cleared this
indicator and, through my inclusion below, now make this
report public.

Second, 2.0 (as well as 2.1) are Historic.  You should
encourage your packager to provide more recent versions
of OpenLDAP Software, such as the latest "stable" release.
It contains many security-related fixes that remain in
final releases on the 2.0 and 2.1 branches.
