If we use just plain ldap (not using openssl), the connection times out
rather quickly, and pam tries the next authentication method which works
as expected, and the problem can be fixed. But unfortunately that also
opens up some security risks, since we can't be sure we connect to the
proper ldap server.
I have had this problem with other applications that use OpenSSL, and the
last time I looked at one in detail, figuring out how to get OpenSSL to
time out properly when it's in the middle of its own internal handling was
surprisingly tricky. However, I don't know if this has already been dealt
with in OpenLDAP's client libraries somehow.
