Can't login after Lion upgrade

Sounds like the same problem that I have. Installation on MBP worked fine, but on my MacPro I can't login.

Login screen appears, I can type in name and password, but then nothing happens.

Also it is not possible to login via ssh. A connect is possible, but login fails, it asks for the password again and again.

Currently I try to install Lion a second time via "recovery disk".

Any other hints or advices?

Start up your Mac while holding the Option key and select the Recovery partition. There will be a Utilities menu with an option to reset your password.

Did you try 1234?

The latter seems to work for me.

I have a different problem...i got this message..The software could not be verified. It may have been corrupted or tampered with during downloading.

I have had some panic shut downs but snow leop has been working ok lately.. now I got this. I guess I ll have to reformat the disk and download from a back up but how do i get lion back? i have not been able to contact the store to at least get my money back until i can install it.. any help?

I have just expereinced the same issue. I have a work around for you.

If you have a Snow Leopard Install CD you can boot from that by holding the C key upon boot up or hold down the option key and select the install CD.

Once launched select continue and then select your language. You will then have access to a tools/utilities menu where you can reset passwords. You select you System Disk and you will notice that you accounts are still missing however you should have access to re-set the root account / pw. Set it to a secure password - after all this is the highest level account on your machine.

Once done - restart into lion again and login into the root account. Username root with password you specified earlier. Once logged into the system - you should still find your old user folder still intact. I would suggest re-naming this account and add suffix _original if you intend on creating a new account with the same name. The username of the folder is based on the short name you input when you create an account.

You can then go into system preferences / users and groups and create a new account with the same short name. After this - I renamed the new user account to _delete and renamed my original account to its former name by removing the _original (as i kept the same short username) Log out and login with your original account - it may ask you to sync your keychain if you have changed your password from the original - in this case provide the previous password.

This worked for me - good luck.

I agree this is unaccaptable for Apple to release an upgrade with a bug like this. Good luck - hope it works for you

I'm right there with you. I have tried all the tips on the forums so far; still no luck logging in since passwords are rejected even after being reset.

It sounds like some people have had good luck with starting up holding down the option key.

i modified my password to blank and got locked out.

after reboot still system wont let me get in with old or new blank password

BUT

with Lion - OS did allow me to reset my password using AppleID from the Login screen

I upgraded to Lion Server from SL Server and now it rejects my Admin Password

did you try rebooting & after few tries - it asking if you want to reset with a AppleID?

Worked for me, thanks, Josh. I knew the first couple of steps, only needed your timely reminder for the confidence to see the process through efficiently.

I did find it necessary to hold down the Option key on startup to access the Snow Leopard DVD, which took several seconds longer to appear than the internal drive, Lion's "Recovery HD", or the external drive (a clone of the pre-Lion Snow Leopard boot drive).

Perhaps curiously, one of my two alternate accounts did appear in the list of available accounts to reset.

open terminal> copy and paste this:

sudo launchctl load -w /System/Library/LaunchDaemons/com.apple.servermgrd.plist

enter your password

Done!

Awesome! Thanks JohnHorton1983. Your solution worked like a charm.

Got right in.

Dear JohnHorton1983. That is amazing! This issue appeared out of nowhere (refusing to let me login to Server) and your fix corrected it at once. Many many thanks!
