Inquiry for Linux RHEL 8.x. support for TPAM

To whom it may concern,

I know that TPAM products have become EOS, but i would like ask for advice due to the customer's request Linux RHEL 7.x. There is no problem with verifying and changing passwords in the version.

However, in RHEL 8.x. version, password verification and change fails. TPAM version is 2.5.914.0190. Please advice.

Kind Regards,
