Joomla allows you to use your Mac OSX Server 10.6 native Open Directory for authentication at joomla's front door. This is ideal because it gives the users of your school or company direct access through the front door. You will need to enable the standard joomla 1.5 ldap plugin, which came with the installation software. The trick is to use correct settings for the standard LDAP--if there is such a thing. At a minimum you will need to set: (Suppose my FQDN is myserver.mycompany.com)

Details : Public
host: myserver.mycompany.com
port 389
LDAPV3 YES
Negotiate TLS NO
Follow Referrals NO
Authorization method: Bind and Search
BASE DN dc=myserver,dc=mycompany,dc=com
Search String uid=[search]
Map: Full name cn
Map: E-mail mail
Map: User ID uid
Leave the other field blank for now.
====

In Work Group Manager create a test user with:
1) Only one short name. If you have multiple short names like "bill," try using "bill.list"' when testing the front door at joomla.
2) The user MUST HAVE an email address in WGM, accounts, user info. Joomla needs to get back at least one email otherwise the authentication will fail.
====

If you get that to work, you can reduce the search time by limting the ldap search.
Authorization method: Bind Directly as User.
User's DN: uid=[username],cn=users,dc=myserver,dc=mycompany,dc=com
====

If you want new users to be created in the ldap server, you will need to authorize to the LDAP directory with:
Connect username and password. I did not try this. 
There is a way to map LDAP groups to the groups used by joomla. This would enable you to give say: author permission to a user directly from WGM. I have not tried that.

Why does adobe reader crash when when I run it from a server based home directory?

- Bill TX

Adobe knows about this problem and at times has fixed it in different version. It appears not be a priority for them, because after an upgrade it stopped working again.

The problem lies that adobe uses the home directory to store some cache data. Apearently the compiler they use can handle the network drive. It might have to do with the copy write version of adobe writer, which might share part of the same code-base. Anyway, the directories that seem to be the problem are /Users/Shared/9.0_x86/ or on the old ppc /Users/Shared/9.0_ppc/ . During various version we have been able to work around this problem by using symbolic link to fool reader to think it is running from on a local hard drive. While this worked for a while, various update tend to break this.

The solution we can offer at this time is to use mobile accounts, which are on the local hard drive. Of course this might not solve the backup problem in your situation and seriously tasks the server storage in situations were users often switch computer. Also one needs to implement a strict monitoring policy to make sure the mobile accounts are sync.

Can you help me install mindstorm on my new snow leopard computer?

- Mary P Cambridge

There is a bug in the mindstorm install disc. I am not sure why mindstorm did not post a fix on their website.  The issue is that the installer removes the installed program during the post flight section. People have find that bey removing the PREflight section the POSTflight program leaves the installed program.

As you can not remove anything from a DVD, you'll need to copy the installer, to your hard disk, remove the preflight section.and do the install here is how:

1. Copy the everything from the MINDSTORMS CD to a folder on your hard drive (desktop will do). 
2. Open that folder and look under “Parts”. 
3. Locate MindstormsUnivEdu.pkg or MindstormsUnivRet.pkg. 
4. Right-click (control-click) and choose “Show Package Contents”. 
5. Navigate into the Contents » Resources directory and delete the “preflight” file. 
6. Close this package and run the meta-package (LEGOMindstormsEngRet.mpkg) from the desktop to install MINDSTORMS NXT.

This should do it.

After you are done you may remove the install folder.
