Up until a few hours ago I was able to ssh to my pix firewall and login with my tacacs account. It mysteriously stopped working. My account isn't locked and I can ssh to the standby ip address (the failover pix) and log in via tacacs (proves routing, ACLs and TACACS works). Any ideas why this happened and what I can do to fix it? I've compared both configs (from primary and failover firewalls) and they are exactly the same.
I can not tell from your post whether you are accessing the PIX from inside or from outside? Can you clarify?
Is it possible that the primary PIX is having a problem with one of its interfaces that might impact the access to the device (so that it never attempts to authenticate) or that interferes with the attempt to authenticate?
On the TACACS server do you see authentication attempts when you attempt to SSH to the primary firewall?
