ora-28040 No matching authentication protocol when running 11g RCU against 12c DB

fabryddorf-OracleNov 22 2021

Hi Guys,
Need to create the metadata schemas through RCU 11g on a 12c DB and getting the above error.
The RCU was downloaded from
https://www.oracle.com/middleware/technologies/bi-downloads.html

Checked the forum and saw many reported this error, but did not find a solution yet.
Updated all the sqlnet.ora with
SQLNET_ALLOWED_LOGON_VERSION_SERVER=(12a,12,11,10,9,8)
SQLNET_ALLOWED_LOGON_VERSION_CLIENT=(12a,12,11,10,9,8)
Tried to run the RCU from D:\ORA\MWFR\12cappr2\oracle_common and there I getting the below error
Unable to connect to the DB. Check if DB connection details entered are correct.
Invalid username/password.
Enter valid username/password

I have correct credentials as I can login into sqlplus without any problem.
Any suggestions?
