A PSM Session to an AS/400 is not automatically logging in as configured in TPAM. It may appear as if no credentials have been passed to the PSM Session.
The AS/400 "QRTMSIGN" value may need to be set to "VERIFY" to allow auto login.
Password contains $ sign.
Test with the QRTMSIGN variable configured to be "VERIFY".
Refer to the Operating System documentation to configure this variable. Depending on the Operating System configuration, this may need to be configured to "VERIFY" to allow automatic login via PSM.
Remove the $ sign from the password rule
