When PAM End-Users are executing a custom A2A script they are getting the return code of 407, which means:
Invalid parameters specified.
A2A Version 4.12.3
In order to run their custom script, the end-user needed to set certain Linux SHELL variables, which they were doing in their script.
However, since they were executing it in their default Linux SHELL of /bin/csh (C SHELL), which didn't have the 'export' command in their $PATH, so it wasn't properly setting the required variables and was the root cause on why it was failing. Therefore we updated the first line to either #!/bin/sh or #!/bin/bash which had the export command their $PATH everything worked successfully.
