iMac not logging probably due to keychains problem
iMac OS X Lion here.
I have two accounts in the iMac. Both with password.
I'm not sure what happened, but now, when I startup the iMac, when I try to enter the first account, I enter the password, the screen goes blank for a moment, and throws me back to the login screen. No messages pop up.
But I CAN enter my second account.
What am I supposed to do?
Edit: More info I remember I was messing with that account's keychain stuff (keys/certificates/etc), possibly deleting keys or even replacing them with other keys etc... Maybe that's related.
