Once in a while an issue comes up where application A gives some odd errors in eDirectory but those errors seem to be cosmetic as application A is still fine and works (unless you count the messages in ndstrace). What does this mean when you see a -714 from eDirectory while tracing LDAP that is talking about some "iterator"? What does an LDAP error 51 mean when everything still seems to return properly? Today I am going to try to share some information on Virtual List Views (VLV) by explaining what they are, how you can use them, and a few cases where they do not work with eDirectory.

Do you have Macintosh users authenticating to their OS X workstations through eDirectory? Use this loginHook script to grant them access to the local machine by group and to populate GroupWise with their PO login settings.

For a while now I have wanted to see how many controls eDirectory really could handle, even if they were not supported. It should be mentioned loudly and clearly that as of eDirectory 8.8.5 some of these controls work but THEY ARE NOT SUPPORTED so if they do not work properly submit a bug or an enhancement but don't expect a quick response. Also for some of these there are definite limitations with how they work. I'll try to cover those as I go.

Last week I was asked if there was a way to start an application at the command line and later come back to it from somewhere else. Normally in Linux/Unix (*nix) it is possible to 'background' a process and then return to it later on but that's only if you are still in the same session where the process was sent to the background. This is useful to have something run while you do other things but reconnecting to this session cannot be done with just the shell. Thankfully 'screen' is on Linux systems by default (all of them I've used anyway) and as a result, Linux Just Does That.

With Novell Support Advisor (NSA) it's possible to retrieve data from your servers, but entering in all your servers takes too much time. How many people will it take to find and insert all your options from which to gather data? With one open source tool and one line of script, just you and a minute of your time.

Do you have a daemon running on your Linux server that you can't afford to have down for any length of time if it crashes? If the answer is yes, then read on!
