Using openldap libraries for connection to Microsoft AD server with different
software(dovecot\squid) fault tolerance not working with ldaps protocol.

uris = ldaps://host1 ldaps://host2

When host1 is completly down - ldapsearch successfully connects to host2 and get
but when host1 is up, but rejecting connection on port - library not trying
host2 - it just return error - connection reject.

This have been tested with openldap version 2.4.24 and 2.3.43(centos 5) - both
works the same. This behavior observed with ldapsearch, dovecot-imap server,
squid server.
