after erasing the config file and reloading the pix, the following lines are missing from the show run:
Aaa-server TACACS+ max-failed-attempts 3
Aaa-server TACACS+ deadtime 10
Aaa-server RADIUS max-failed-attempts 3
Aaa-server RADIUS deadtime 10
If you try to add them the pix errors giving you syntax is incorrect.
I currently have 3 devices doing this.
they are all running 6.3.5
