Focus On Your Core Competencies

1 Comment

It’s something drilled into every MBA, day after day. It’s a simple mantra, but one easily forgotten as excitement around a project builds. I am always tempted to re-invent the wheel, just to see what kind of wheel I can come up with.

But, when you have a goal in mind, remember: you don’t need to roll your own JSON library, host your own Git repository, code a game engine from scratch. Keep it simple, and focus on what you do best.

PS: Also fight the urge to recode your Java app in C# because Visual Studio 2013 is all free now. Fight it. You can do it!

It couldn’t hurt to see how Mono runs in Centos these days though…

Encrypted, and it feels so good

Leave a comment

Finally implemented SSL for CalypsoAdmin. Authentication was being handled by GSSAPI, so no passwords were being sent in the clear, but it’s nice have all of the LDAP data no longer in the clear.

The initial plan was to use TLS. TLS works fine under LdapContext, but that broke GSSAPI, which works fine under DirContext. For the time being, SSL seems to work fine with DirContext, so I’m putting it to rest until another day.

CalypsoClient for Windows

Leave a comment

The CalypsoClient for Windows is complete. The Windows client will add the computer to LDAP, create the kerberos host/ principal, create a keytab for the princiapl, copy the kaytab over, and join the computer to the Samba domain. ::phew::

Next up: CalypsoControl, and putting that host keytab to good use.

The custom ldap attributes and objectClasses have been created and are loading nicely into ldap. Now it’s time to get some code down for Calypso Control. With a little luck, we could have something very nice to show by the end of summer.

Time for the Custom Stuff

Leave a comment

Having received our OID from IANA, we are now ready start implementing custom object classes and attributes in LDAP. This will pave the way for computer management, email management, and Calypso Control. As of now: Users, Groups, and DNS  are up and running and manageable in CalypsoAdmin. This could be an exciting summer!

DNS management almost done

Addition, removal, and editing of host entries is now done in CalypsoAdmin. Just need to implement domain addition/removal, which will hopefully just work nicely with the existing interface. I can turn JTree nodes into LDAP DN’s in my sleep now.

Javascript no likey fractions

1 Comment

Since Ubuntu 10.04 LTS is on its way, I figured I’d wait on further development of Calypso until it’s ready. Just makes things easier knowing bugs are really mine, and not the fine folks at Ubuntu.

Since this has left me with and abundance of time on my hands, we’ve begun a super-secret project using Javascript and the HTML5 canvas. 1st of all… wow. I can’t believe how easy it is to get some great stuff done. That said, it’s worth noting that when it comes to rendering, Javascript is *incredibly* faster when everything is in nice whole numbers. If things are going really slow, make sure you’re not dividing any odd numbers by 2 :-p

Samba with Kerberos working again

Leave a comment

It turns out that “valid users = …” in smb.conf breaks kerberos logins to Samba. Otherwise it was returning “tree connect failed: NT_STATUS_ACCESS_DENIED”, even though it worked fine with NTLM authentication. Wasn’t falling asleep tonite until I had this one figured out.
