TIMEOUT and NETWORK_TIMEOUT are not applied when trying to connect to a stalled server using SSL. The same scenario works when using an unencrypted connection.
Reproducer: 1) set up a server for use with SSL (localhost connection is enough) 2) set NETWORK_TIMEOUT and TIMEOUT in ldap.conf 3) slapd -u ldap -g ldap -h "ldapi:/// ldaps://localhost" -d1 4) verify that connection works ldapsearch -x -H ldaps://localhost 5) kill -STOP <server pid> 6) ldapsearch -x -H ldaps://localhost At this point, the client hangs and doesn't properly time out.

This bug doesn't seem to be crypto library specific. I reproduced it with both moznss and openssl.
