iChat after Lion--Messaging Agent keeps wanting password

HI,

If this is Lion then go to the FInder > GO Menu and hold the ALT then select the library that appears.

In the Library navigate to the Preferences folder.

Find and highlight com.apple.ichat.Jabber.plist (if it is a google or JAbber Name)

or com.apple.ichat.AIM.plist if it is an Apple or AIM name.

The do a Get Info (Apple/CMD ( or ⌘) and i keys together)

Do you Own the File (Your Name will appear at the Bottom)

Do you have Read and Write Permissions

It could be one of those odd quirks you get with a Beta that, unfortunately others cannot reproduce, that leave you cursing for a while.

I would agree that Mountian Lion does seem to be coming awfully quickly.

I know part of this is due to the fact I did not have a computer to run Lion at first.

I can't think of anything else to try at the moment.

For me, the problem seemed to be due to my chinging my Login password. If you somehow managed to make your Login password different from your "Login Keychain Password" (yes they can be different) you may need to synchronize them. I went into keychain preferences and turned on "Synchronize login keychain password with account' and rebooted my machine. After restart a dialog box asked me to enter my 'old' password. I entered that and all was good in mac world again. So, I googled this and found the follwoing link that may be helpful.

Ok I freaked out too, I was up late with too much coffee and not enough sleep. I messed up my admin password somehow and couldn't remember what I just typed in. Oh well, to make a long story short I needed to Reset my admin. password with the system disc. After that my keychain was going crazy and one of the error messages was the exact one your speaking of. Message Agent wants to use login. After several attempts to totally geek out and try to fix the individual issuer I just deciced to reset the whole keychain. After that everything was all good again. Go to Keychain access in your Utilities foldder then Click<preference, In the General tab there is Reset my Default Keychain Click that and start all over. When you restart it will ask you for passwords for Facetime, I message and all that. But if they are your passwords you should be fine. Also check out http://support.apple.com/kb/TS1544. It will give you the same info but smarter. Hope it helps out!
