Safari can’t establish a secure connection to the server

Question

I realize there is another question with the same title, but my situation is very different.

• The problem started on three of my computers after upgrading from Leopard to Snow Leopard.

• I can login to gmail and facebook using https with no problem.

• I can not login to https://identi.ca/main/login or https://seminars.wolfram.com/ or https://panopticlick.eff.org with Safari, works fine with Firefox.

• Already tried "Safari Reset..."

Any ideas?

Answer 1

I have just solved this problem by following this procedure published by phurd99 in the Apple Support Forums:

1. Open applications
2. Utiliities
3. Open Keychain
4. Click Keychain Access and select Preferences.
5. Click the "Reset My Default Keychain"

(...)

This solves the problem but you are left without you precious keychain (a backup is saved).

Then, using the backup and trial and error I discovered that by deleting one specific certificate, the problem is solved:

UNT-USERFirst-Hardware
Intermediate certificate authority
Note: This certificate is signed by an untrusted issuer

Answer 2

I had this problem as well. Adding new root authority certificates from Thawte fixed the problem. Apple has documentation on how to do this here http://docs.info.apple.com/article.h...en/mh2046.html

I added the root and server certificates that I downloaded from here http://www.thawte.com/roots
