Hi,
Its same as this , already reported .

I see the same issue on an SRX running 12.1X46-D86. After upgrade, J-web login fails,while SSH works fine. J-Web shows the following message- Invalid username or password specified - both for root as well as non-root user login attempts.

Seems to be an issue with this particular Junos version. Will update this thread later, if there is any fix.
