We're an Active Directory shop that has mostly PCs, except for a couple Macs that connect via LDAP. One of those Macs I checked out months ago for some software testing. Turned it back in afterwards. Now, several AD/LDAP password changes later I borrowed it from the user that has it checked out. I'm able to complete the initial login as the LDAP connection seems to work, but then it ties up asking me for my keychain login password, which is apparently my LDAP password from generations ago. Of course, I have no clue which generation, and even if I did, I don't remember any of those old passwords anymore...
So, how do I reset the Apple keychain and make this machine happy again?
~/Library/Keychainsand namedlogin.keychain. You can try to run Keychain First Aid in Keychain Access in/Applications/Utilitiesafter making sure in Preferences that all check boxes in the First Aid tab are checked. Other than that, remove it and create a new one if you don't need its contents? – Daniel Beck Dec 9 '11 at 19:12
