Lion iCal Server and ios9

Hi Folks

Been a while was since I posted on here but in a bit of a quandary with an iCal Server that I inherited from a previous IT company. Its running 10.7.5 Server and all has been well until iOS 9 popped up and now it doesn't want to sync any more.

When I try and setup I get the option to try without SSL but the error I get after that is 'CalDAV account verification failed' Now, when I do the exact same thing on iOS 7 or 8, I get the option to make an SSL exception and then syncing all goes to plan but no dice on iOS 9.

Anyone got any thoughts? I appreciate that I may need to upgrade the server to a later version and any advice on that would be much appreciated.

Thanks!

Chris

Hey Chris, you probably already updated your Lion server, but I have had success changing the 2 instances of SSLv3_METHOD to TLSv1_METHOD in each file below using TextWrangler, using the following steps:

/usr/share/caldavd/lib/python/twistedcaldav/stdconfig.py and

/usr/share/caldavd/lib/python/twext/internet/ssl.py

Steps:

BACKUP YOUR SERVER. You are messing with files under the hood. You may want to export all calendars, too using 10.10 or earlier.

Turn off iCal Service

Open those 2 files in TextWrangler

Change the 2 instances of SSLv3_METHOD to TLSv1_METHOD in each file and save.

Turn on iCal Service.

Try to login using Calendar on a 10.11.x machine (I used 10.11.4). It should fail. If it doesn't you are good to go, but you should also verify a machine with 10.10.x

If it fails, turn off iCal Service again.

Change the four instances back from TLSv1_METHOD to SSLv3_METHOD. Please note in the stdconfig.py SSLMethod line there will be 2 instances of TLSv1_METHOD after the hashtag comment since you changed SSLv3_METHOD previously. It doesn't matter that you change the comment actually, but it's good to remember the options you have.

This is the line I am referring to:

"SSLMethod" : "SSLv3_METHOD", # SSLv2_METHOD, SSLv3_METHOD, SSLv23_METHOD, TLSv1_METHOD

in the stdconfig.py file.

Save the files.

Start the iCal service again.

RESTART the server.

It was at this point that I was able to get 10.11.x and earlier clients to login again into their Calendar and iCal accounts. This also worked with iOS 8 and iOS 9 Calendar app logins.
