Oracle UPK Installation Failed - ORA-12640: Authentication adapter initialization failed

Hi Friends,

I was setting up Oracle User Productivity Kit (UPK) in Server only mode for setting up a dedicated documentation facility. This was my first hand setup experience with the UPK & so as i expected i landed up with few issues during installation.

While deploying the UPK server on a  local server, at the end of the installation, i received error:
ORA-12640: Authentication adapter initialization failed

I thought, there might be some issue due to the database. Went around searched & re-tried the installation, but it again failed due to the same error.

After further research, i found that this error is more related to the Oracle Client settings in sqlnet.ora

Below is the change i did in my sqlnet.ora file after which Oracle UPK Server Mode installation completed successfully: 
Changing this one to:

Keywords: Oracle UPK, Oracle User Productivity Kit, Oracle UPK Installation, ORA-12640, etc
