OK to delete login keychain?

As reported elsewhere, I suddenly lost the ability to log into one of the accounts on my Leopard system (Intel iMac). If you try to log in, the "cube" rotates to a blue screen, and maybe 10 seconds later, the login screen reappears.

I've tried to decipher the logs to figure out what's going on, and the first message that looked problematic was about "unable to unlock login keychain." I don't know what the problem is; I mounted the user account folder on another Mac, and used Keychain Access to make sure the keychain password was the same as the login password. This didn't change the behavior at all. And I wasn't able to make Keychain First Aid on the remote Mac operate on the problematic keychain on the iMac.

My next idea is to simply delete the login keychain and hope that it will recreate it when I try to log in. Am I courting disaster?

Failing that, my next plan was to create a new user account and copy the home folder from the old one to the new one. Any tips on making that work?

Intel iMac (late 2007), Mac OS X (10.5.5)

deleting the login keychain is completely safe to do. however, it will have no effect on your problem. a bad keychain can not prevent a login. you might have some bad preference files or corrupt caches somewhere. try running [Onyx|http://www.apple.com/downloads/macosx/system diskutilities/onyx.html]. run all maintenance scripts in the Automation tab including system cache cleaning.

see if that helps.
