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.
