Can not remove SSL certificate on iPhone 6 - iOS10.2
Posted on 2016-10-19
Only one iPhone is having this issue.
We manage access to our email and internal site via SSL certificates.
These are installed through Airwatch MDM profiles.
Usually, if I remove an iPhone from Airwatch, it will delete all certificates and profiles on that device.
However, for this phone, it appears that all certificates are removed (Settings -> General -> Profiles does not exist) but the phone can still access the internal site.
If I clear out Safari's history and website data and I then try to access the site, it will prompt for the certificate by name (firstname.lastname@example.org) and selecting it opens the site.
List of what I've tried to remove this certificate:
Go to Settings -> General -> Profiles (this option does not exist)
Clear out History and Website Data for Safari
Reset Network Settings
Reset All Settings
An annoyance caused by this, is that when I install the Email profile which contains the certificate from Airwatch, the device now has two of the same certificate. So whenever the user attempts accessing the site, he is prompted to select which of the two he wants.
This prompt also appears if the site has been unused for about 5 - 10 minutes.
Any ideas on how I could either:
1. Remove the duplicate certificate stored on the device or
2. Force Safari to use one of the certificates without prompting the user
