[0.2 alpha] LDAP Verisign example comes up blank

[bitman]

When I enable the example verisign.com LDAP server, it comes up blank in Roundcube.  I've verified the server works using 'ldapsearch' under Linux.  The LDAP code doesn't seem to do any logging, so I have no idea if the server is being queried.

Also, the forum admin needs to add a prefix for the new 0.2 alpha release.
