I've googled on this problem and found a number of situations, none of
which has given me a lead to solving my problem.
On our certificate server, running Openssl v0.9.7f, I have created a
self signed CA certificate which so far has worked well.
Now I'm setting up an Openldap server as follows: It's running RedHat
Enterprice Linux v4, Openssl v0.9.7a and Openldap v2.2.13. I've had any
amount of trouble making sasl work and given up in favour of TLS. Now
I'm having problems with this and it seems to be related to the validity
of the CA certificate.
