The database requires the wallet even if no SSL (Secure Sockets Layer) is used to secure the connection between the database and the directory. If SSL is used, then this wallet should be used to store the database's digital PKI certificate.
The wallet password you enter when using Database Configuration Assistant to register a database in the directory is the password to the wallet itself. This password is not the database's directory login credentials.
You can change this wallet password later, using Oracle Wallet Manager. However, if you forget this wallet password, then you must generate an entirely new wallet and password. To do so, you must first delete the existing database wallet, create a new wallet (which can be empty) and put it at the default wallet location, $ORACLE_HOME/admin/Oracle_SID/wallet (in UNIX environment). Next, unregister the database from the directory, and reregister the database in the directory. During that registration, another database wallet and password can be generated.

After you have prepared the directory for Enterprise User Security, then you can create the Enterprise User Security database and directory objects as described in "Configuring Enterprise User Security Objects in the Database and the Directory (Phase Two)".
