I purchased Lion Server on Mac Mini and last night I proceeded to play with the Server App. I placed a password on it all was good. Tonight when I tried to sign onto Server the password was remembered but I can't sign in. I removed the password and signed in manually with the same result. I checked the password stored in Keychain Access and it was the password I entered in last night. It is the same password I use to sign onto the Mac Mini. What can I do so that I can sign onto Server? I also noticed that when I try to send email in my Gmail account in Mac Mail I receive the following error: An error occurred when trying to sign this message with a certificate from *&&^@gmail.com. Verify that your certificate for this address is correct, and that its private key is in your keychain.
