      We have several bug reports [1][2][3] that SOCKS proxy settings don't
      work, however there is a preference page [4] in Studio which gives the
      impression it's supported.

      That preference page is provided by Eclipse. What is does is to set Java
      system properties [5]. There are known limitations, e.g. socks
      authentication and proxy bypass don't work [6]. There is no additional
      code in Studio to support proxies, and also zero tests.

      In the past with JNDI the basic settings of a SOCKS proxy worked because
      it is handled by Java old blocking IO.

      However after the JNDI removal we only support the LDAP API which uses
      Mina and new IO where those system properties don't work [7].

      I'd suggest to remove that preference page and related documentation
      because its presence gives users the impression it would work.

      Remains the question if we should implement proxy support properly in
      Studio. It's clearly possible, Mina even implements a proxy filter and
      connector. However it's significant effort and requires changes in the
      LDAP API and new UIs in Studio and proper unit/integration testing. On
      the other side there are dedicated tools which provide transparent SOCKS
      proxy support. So I have doubts if it makes sense to implement it in
