Re: Apple Devices not trusting Comodo SSL Certificate on initial Wireless Connection

[Jim Williams Jr <Jim.Williams () PCT EDU>]

Thanks for the info.  Our cert actually does match up with the apple store serial number.  I double checked with the 
link that you sent to verify that serial number “00 e8 2f 6a 34 a8 9b a6 49 f8 f8 1a 52 46 5f cc 56” was listed.  Maybe 
the solution would be to just buy a cert from another provider.  I was hesitant to do this though, didn’t want to waste 
the money if the same problem would result.

Hi Jim,

We have the exact same problem at Mills College. It turns out that the Comodo Cert in Apple store has a different 
serial number (it is older) than the cert we purchased.  We tried installing an older cert that matched the one Apple 
has, and that fixed the issue for Apple devices but broke the trust for all other devices, so we reverted.

Here is a link that will show you what Apple has in their Trust Store:
