LastPass authentication not working

Hello,

What is your Remote Desktop Manager version and datasource type?

Best regards,

RDM version 2024.1.32
Datasource MS SQL

Hello,

If you give it a try with the latest version of Remote Desktop Manager, do you have the same behavior? : https://devolutions.net/remote-desktop-manager/home/download/

Best regards,

I'll give that a go, but it seems strange that all instances stopped working at the same time. Could there be an expired token between RDM and LastPass?

Upgraded RDM to 2024.2.10
Same Error trying to connect to LastPass

The error comes after entering the MFA response

Same issue here with multiple users, we did 2 upgrades today (june 10 to june 17 to june 18 versions) and had issue with all 3.
application log:

Hello,

Thank you for the application logs, this will be very useful for us to figure out what is causing this issue.

We have opened a ticket and will post back here as soon as we have an idea of what is going on.

Regards,

Bump. We're experiencing this now too. I've opened a ticket, but wanted to post here too to see if ya'll have found anything yet.

Hello,

We've identified the issue. This is due to LastPass beginning to roll out encrypted URLs (you can find out more about this here: https://blog.lastpass.com/posts/2024/05/lastpass-is-encrypting-urls-heres-whats-happening).
The reason we didn't stumble upon this before is because not all accounts have their URLs encrypted. New LastPass accounts have encrypted URLs by default, and for existing accounts, they seem to be rolling out the change progressively, and it's only now affecting you. This would also explain why we couldn't reproduce in our environments with our existing accounts, but we were able to with a new LastPass account.

We will have a fix for this in 2024.2.12.0. We will see if we can release this version tomorrow, otherwise it may have to wait until next week, as it has to go through our QA process.

Regards,

Good job on identifying the issue quickly! We'll be keeping an eye out for that release.

Additionally, if you need a quick workaround, you should be able to replace the PasswordManagerAccess.dll file in your RDM installation folder by the one I've attached to this post. This is the DLL that will be available in our upcoming 2024.2.12.0 version, so this could be a way for you to have the fix before we're able to fully release this version. Note that the version of the DLL file attached should say 16.2.0.0.
I recommend backing up your current file just in case, but it should be as simple as dropping the file in your installation folder, replacing the old one.

If you try out this DLL with the fix, let us know if this helps, otherwise, please let us know what the error is and what's in your application logs.

Regards,

Replacing the DLL fixed the issue for me and a colleague.

Thank you for the fast fix on this issue

Replacing the DLL fixed the issue for me. Thank you for the quick response.

Replacing the DLL fixed it for me as well. Good work guys!
Note for others: If you do the update of the 20th afterwards (2024.2.11.0), you'll have to replace it again.

Thanks for the feedback everyone, I'm glad this could help while we are preparing our next minor update.

Regards,

DLL fixed it for me

Same here, replacing the DLL did the job!
Thanks.

Hello,

Version 2024.2.12.0 containing this new DLL with the fix should now be live. Please let us know if you encounter any additional issues with the LastPass integration.

Regards,

Just updated to 2024.2.12 - lastpass integration now works :)
Thanks again!
