"ORA-12534: TNS:operation not supported" , LDAP User using external password store wallet

Hi,

I'm on 64bit RHEL8 sever, using 32bit 19c oracle client ( we are running sqr, so we have to use 32bit oracle client) and we store database username/password in a oracle wallet.

I get "ORA-12534: TNS:operation not supported" when trying to connect to our database. And it only happens to external users on the server. In other words, the user is not defined in /etc/passwd file.

ERROR:
ORA-12534: TNS:operation not supported

Enter user-name:

*******

It works on our old RHEL7 server. So I suspected some new patch broke it. So I applied following patches in order to the 32bit 19c oracle client home on our new RHEL8 server.

Howdy, Stranger!
