Creating externally-authenticated accounts for users
To enable the external authentication method for a user, use the CREATE USER or ALTER USER statements.
Before you begin, make sure that you have administrator privileges to enable external authentication for a user.
To create an externally-authenticated user account, complete the following steps:
1 Complete the steps to configure your environment for external authentication, see Configuring externally-authenticated accounts.
2 Either create a new user account that uses external authentication, or convert an existing user account. In either case, username must match the user name of a user that has an operating system user account.
▪ To create a new user account, use the following syntax:

CREATE USER username IDENTIFIED EXTERNALLY
▪ To convert an existing user account, use the following syntax:

ALTER USER username IDENTIFIED EXTERNALLY
