SGD 4.40.917

Part of the graphics subsystem of SGD is based on the X.org project. Well because of a security vulnerability there is a re-released version of SGD now available.

Version 4.40.917 is now available and includes 2 significant additions:

  1. The X.org security fixes.
  2. Support for Windows Terminal Services Session Directory.

This second is a feature that wasn't due to arrive until the next release but the team took the opportunity to include it as part of this rebuild.

This is good news, especially for people using a mixture of Sun Ray and non-Sun Ray clients.

Speeding up LDAP queries when using Web Authentication

Some time back we discussed how to speed up LDAP authentication when logging into SGD. In this tip, we simply recommended reducing the user attributes that we search in order to authenticate a user given the provided credentials.

Well, nice tip as it was, it only works when you are logging in directly to SGD (using built-in authentication) and doesn't help if you are using Web Server Authentication. e.g. you're using something to protect the /sgd URI for example, a simple mechanism like Apache basic http authentication (.htaccess), or something powerful like Sun's Java System Access Manager to protect access to the /sgd URI.

If you're doing this, you need to configure an additional bean in the SGD system. And, to preserve your sanity, Fat Bloke recommends always keeping them in step by configuring them together:

/opt/tarantella/bin/tarantella stop
/opt/tarantella/bin/tarantella config edit --thirdpartyldaploginauthority.properties-searchAttributes cn mail
/opt/tarantella/bin/tarantella config edit --searchldapla.properties-searchAttributes cn mail
/opt/tarantella/bin/tarantella start

Sorry not to have mentioned this earlier ;-)
