slapd has random connection failures related to "do_extended: protocol version (2) too low"

[Ian Gordon]

slapd seems to have random connection failures.

The log files show

Jul 18 14:01:57 simpson slapd[24409]: conn=1387 op=0 do_extended: protocol version (2) too low

for every connection failure.

The same command will succeed 99% of the time but will fail occasionally.

The command I used to test the problem was:

ldapsearch -x -H ldaps://host.domain.ac.uk/ -b dc=domain,dc=ac,dc=uk uid=ig

I found a reference to this problem at http://www.openldap.org/lists/openldap-bugs/201112/msg00019.html for ITS#7107

I have applied the specific 1 line GIT update to the package source and everything is now working properly.

It would be nice if the patch to fix ITS#7101 could be applied to the slapd package.

Thanks for any help you can be.
