ICal and Kerberos - works sometimes

Hello everyone... Looking for a Kerberos expert.
I'm trying to get single sign on to work for iCal services. I have it working on a macmini server that is a brand new installation... bare bones set up (Address Book, AFP, DNS, iCal, OD). However, I can't seem to get it to work on an actual deployment on an Xserve. And I have no idea what the key difference is between the two setups.
It seems there's a lot of unanswered chatter on this topic... Can anyone help?
Thanks,
Jon

So I think I've discovered that not all services are kerberized... Not sure how this happened. I even recently rebuilt Kerberos on the xserve. Anyways, I noticed by checking the Kerberos services that a few key services to CALDAV (what iCal is using) are NOT listed on my XSERVE set up (such as HTTP and XMPP) and they are listed on my mac mini set up. This would explain why Kerberos shows as "running" on the xserve, but iCal can't use it to authenticate.
To check which principals are attached to Kerberos try this...
sudo kadmin.local -q list_principals
(You'll have to authenticate, of course invoking sudo.)
So now, I think my only option is to try and rebuild Open Directory. Which seems a little insane considering that Server does not need kerberos to work... just have to decide if it's worth the potential dain bramage that could follow trying to get 15 users re-imported and working properly with a new OD master. Any feedback on how to do this without too much trauma? I have clones of the working server hard drive and can make a clone of server data hard drive which houses all the home folders for my users. Again... any help would be very much appreciated.

In Flex application functionality is working sometimes and not working sometimes..

Hi,
Please help me on this..
In my flex application some functionality is working some times and not working sometimes..
In my project i have 5 sections with 5 separate screens..Each screen is of one diffeent module.
After logining into the application:
I will go to one screen..First time every functionality is working in that screen..
Ex:: I have a screen with datagrid.From that user will select one job name from datagrid click on next button..
Based the job name the user selected i have to display some information in next screen and customer names.customer names is a combo box..
below is the code:::
               public function populateAllOEMCustomers(event:ResultEvent):void
        1)     var object_CustomerList:CustomerList = event.result as CustomerList; //Assigining result object values to Object reference variable.
          2)    var allOEMCustomersCollection:ArrayCollection = new ArrayCollection(); //Declaration ArrayColliction referance variable.
         3)       var i:int=0;
         4)      var customerComboLabel:Label = new Label();
          5)      for (i = 0;i < object_CustomerList.arryCollCustName.length; i++)
                    var strCustName:String = object_CustomerList.arryCollCustName.getItemAt(i).toString();
                    var strCustId:String = object_CustomerList.arryCollCustId.getItemAt(i).toString();
                    customerComboLabel = new Label(); //Dynamic declaration of label.
                    customerComboLabel.name = strCustName; //Assinging the customer name to the Label name field.
                    customerComboLabel.text = strCustId; //Assingning the customer id to the Label text field.
                    allOEMCustomersCollection.addItem(customerComboLabel); //Adding Lable into the ArrayCollection referace variable.
                //customerComboID.selectedItem = "--";
                OEMCustomersComboID.dataProvider = allOEMCustomersCollection;
                OEMCustomersComboID.selectedItem = -1;
This functionality is working fine when i visit to this screen first time..If you go back to another screen and come back to this same screen and click on next button this time customer names combo box has no customer details..I am getting Nullpointer Exception and it is showing the line number 5( i have given the number for code given above..)
If i change the first line of the code to below code:: every time the above functionality is working fine.Not getting any error msg..
var object_CustomerList:Object= event.result ;
If i type cast it to specific class(CustomerList) ,functionality is not working ..getting null pointer exception..If i type cast it to Object everything is working fine..In my code wherever i have typecasted it to specific class functionality is not working(gettingNullpointerExcepion).
Please help me on this..I am not getting what could be the reason..
I am using::Flex 3,Flash player 10.1
Thanks in advance..

Hi Satya,
This sometimes as in your case might not work as the way you have specified the RemoteClass attribute in your AS class. As somtimes there may be a case as before it is mapped to a server side you are returned the data and so that you may not get the data as your Custom class but as normal Object type.
So in order to avoid this you can map the server side class to AS classes in the PreInitialize handler itself as shown below:
Specify the preinitializeHandler in your main application and write the below function.This way also you can map AS classes with the server side. So that you will not have any problem referring your application as AS class types.
You can use the same line for registering all the classes. By using this you can remove all the [RemoteClass] attributes on all AS classes and include it at single place.
preinitialize="onPreinitialize()"
private function onPreinitialize():void
registerClassAlias("com.expeditor.ScriptAdmin.Objects.CustomerList", CustomerList);
Here in the above line of code the string in quotes refer to the namespace of the Server side class and the latter is your AS class. Also dont forget to import the namespace of the corresponding AS class in the file.
Try this and let me know..
Thanks,
Bhasker

AOL and iChat work sometimes

I am trying to figure out why AOL and iChat work sometimes and other times it doesn't. I am trying to video chat with a family member and some of the time I can make a connection just fine and other times we get error code 8. If it was a firewall issue wouldn't it never work?

For the last several days, I haven't been able to log onto my screen name. I have a mac book pro and have kept my aim screen name and used it for my ichat as well. I have done this successfully for the last few months.
But now every time I attempt to log on to my ichat or aim I receive the same error message. "You have attempted to log in too often in a short period of time. Wait a few minutes before trying to login again." I waited about 10 minutes before attempting to log into ichat again and the same error message came up. I waited an hour and then attempted to log onto aim and the same error message appeared. I then decided to wait a day and try on a different computer and the same error message appeared when I attempted to log into my aim screen name on the mac and the dell computers.
However, I am able to log onto both ichat and aim using my friend's screen name. Therefore, it appears as though the problem is with my screen name and not with the computers connection or with aim as a whole. I really need to use the screen name as I have had it for over ten years and don't want to change it at this stage. Please help me fix this problem as I seem to have attempted everything.

ICal and Kerberos

I'm having some trouble adding an iCal account using Kerberos as the authentication method. It has been working up until today. Kerberos seems to be working correctly (it's granting tickets successfully, anyway), but when I try to add an iCal account, I get the message: "Your password was rejected by the server server.foobar.com for the login x", where x is my username. Open Directory is on and functional.
iCal service log reads:
+2009-02-02 20:45:55-0500 [-] [caldav-8009] [AMP,client] "Directory service <SudoDirectoryService '/Search': FilePath('/etc/caldavd/sudoers.plist')> has no GUID; generating service GUID from realm name."+
+2009-02-02 20:45:55-0500 [-] [caldav-8009] [AMP,client] PROPFIND /calendars/_uids_/D2819CDB-C0DA-455B-8A8F-924D1C6AEA4D/ HTTP/1.1+
+2009-02-02 20:46:50-0500 [-] [caldav-8009] [AMP,client] Unauthenticated users not enabled with the 'calendar' SACL

I have found a reliable and somewhat fast approach to restoring Open Directory master is to export your User profiles, Group profiles and computer profiles from WGM.
Stop Calendar services. Take OD to standalone and then repromote it to master. Import the user, groups and computer profiles with WGM. Check your server's ethernet mac address in computer/inspector to make sure your directory is using the right address.
Reenter the user passwords and re-enable your groups for wiki/blog services on your server. This will return all users and groups with their previous UIDs and GUIDs so that data files will be associated with the right person/group.
Restart your iCalServer. Restart web service.
Other services such as afp, and mail will remain online and offer those services to the users once their passwords are restored.

Todo for ical and iphone

I use the to do list with ical and it works fine, but it doesn't sync with my iphone.
Can anyone recommend an easy to do package that integrates with ical to do and can be synced and updated on my iphone??
Thanks in advance.
M

I don't think there is a way to this. I wish apple would make the todo list available and syncable with the iphone. How do we get apple to do this. It is such a pain not having this feature. The other thing that I use is quickcal as a way of putting info into ical. Its a bit buggy though unfortunately. Be great if apple made a good widget version of this that worked well.
Sorry I can't be of more help

ICal and AirSet

I subscribed to my web-based AirSet calendar in iCAL and it works fine except that when I have multiple appointments at the same time in my AirSet calendar only one has a normal appearance. The rest show up as ghost images behind the normal appearing one. I can correct the problem by changing the start times by 1 minute on AirSet but I am hoping for a better solution.

This will fix it:
1. Open iCal and backup your entries. Make a note of the fie name and location, you're going to need them in a minute. Once your backup/export is completed, close the iCal application.
2. Open Finder and remove everything inside the "Username/Library/Calendars" folder. For instance, if your username is "Joe", then move everything inside the "Joe/Library/Calendars" folder.
3. Open the iSync application. It's located in the "/Applications/" folder. Once iSync is opened, go into the iSync Preferences (iSync -> Preferences) and push/click the "Reset Sync History" button. Then, close the iSync application.
4. select the file your created earlier. Dbl click on it.
5. Open the iTunes application and connect your Apple iPhone to the computer.
6. Within the Advanced section of the Info tab for the Apple iPhone, check the box the overwrites/replaces the Calendar data on the Apple iPhone.
7. Click the Apple/Sync button. New, modified and deleted entries should now be syncing correctly.

I recently began using reminders in ical and downloaded the iPhone and iPad app. It works great. However, the reminders in ical on the COMPUTER is difficult to work with - thin long column on the right rather than in it's own screen. is there a reminders app for the COMPUTER that is more user friendly?

sgreenie,
If you are willing to wait, Apple - OS X Mountain Lion - Inspired by iPad. Made for the Mac explains that a "Reminders" application will be included in the next release of OS X.

My iTunes v.10.6.3.25 is intermittently refusing to open. Sometimes re-booting my laptop works, sometimes not. I just put the computer to sleep, and when I woke it up, iTunes started automatically. Any thoughts?

My iTunes v.10.6.3.25 is intermittently refusing to open. Sometimes re-booting my laptop works, sometimes not. I just put the computer to sleep, and when I woke it up, iTunes started automatically (I had been trying to open it just before by clicking on a song file in my Documents window, and that's the song that started playing when the pc woke up). I went to my iTunes Help and clicked Updates/download iTunes 10.7 twice, but got nothing. Now, Im wondering if I should downloacd the entire 10.7, or whether that would overwrite all my files, erasing my songs. Anybody know? Thanks.

Hey thanks for replying.
Here's what I did:
First I tried the Winsock reset in the Command prompt. Nothing changed.
Next, I tried the instructions on http://http://support.apple.com/kb/TS4123. The only other program that came up on the 'Winsock Providers' tab on the program was 2 Windows Live applications, which I can do without. So I deleted all Windows Live Applications.
I did the Winsock reset in the Command Prompt again and rebooted my comp.
Unfortunately, nothing has changed. iTunes keeps freezing at various stages of the sync, then shows the candy cane-striped bar with either the words 'Finishing sync' or 'Cancelling sync', before showing the Apple logo.
Sometimes, iTunes gets to the syncing stage - "Copying # of ####" - where it will trudge through the first, second and third tracks before flashing "Copying 4 of ####" for a split second and I catch "Cancelling sync" briefly before the Apple logo appears.
Again, I've repeated the steps I mentioned in my previous post. Does ANYONE know when the new version of iTunes is set to be released?! This one is driving me INSANE, to say the least!!

ICal and Address Book quit working on iPod Classic.

iCal and Address Book no longer sync to my iPod Classic. Why did this stop working? Anyone else have this problem? How can I fix it?

I reinstalled the operating system and the computer now syncs fine.

Yes, you can create separate calendars in iCal, and have them sync separately. All controlled inside iTunes when you sync your phone, or Mobileme.
