I was able to get working with a signed certificate from an authority.
Took a bit of work to find the right format and right certs to work with iOS, but it is now working.
Thanks everyone for your help.
If one has 50 or so Directories in the GW Client; Only 23 are displayed in the Mobility IOS directory listings. The same goes for changing the position of a directory in the GW Client, the change is not reflected in the mobility iOS display. - Thoughts?
I have some newer iPhones that are on iOS 13 and we do use 3rd party cert and those iPhones had no issues with connecting after the upgrade tio iOS 13, so I concur that the self signed certificate was likely the issue for you.
can you not just go to server:8120 port and login as the user
Then add the certificate from there, go to settings the cog, click in it , download the certificate and then allow it on the device?
