ORA-28041: Authentication protocol internal error

Expired user accounts can't change password and connect from 11.1.0.7 client to 12.2.0.1 DB+April2018PSU, failing with error 


ORA-28041: Authentication protocol internal error.

There is no issue with open user accounts connecting from 11.1.0.7 client to 12.2.0.1 DB+April2018PSU.

Also the expired user account connections from 11.1.0.7 client to 12.2.0.1DB+Jan2018PSU works fine. The issue started only after applying April 2018 PSU patch on DB server.

From Forms 11.1.2.2 and the SQLPLUS 11.1.0.7 that comes with Forms 11.1.2.2, expired user connections fail with below message:

ERROR:

ORA-28041: Authentication protocol internal error

In 12.2.0.1 databases, 11.1 client support has been removed. The following table shows which client and which database version are supported.
