All remote subcommands require that credentials be specified in terms of an administration user name and its password. By default, the domain is created with an identity that allows an asadmin user to perform administrative operations when no identity is explicitly or implicitly specified. The default identity is in the form of a user whose name is admin and has no password. If you specify no user name on the command line or on prompt, and specify no password in the --passwordfile option or on prompt, and you have never logged in to a domain using either the login subcommand or the create-domain subcommand with the ----savelogin option, then the asadmin utility will attempt to perform a given administrative operation without specifying any identity. A server (domain) allows administrative operations to be run using this default identity if the following conditions are true:
1. The server (domain) uses file realm for authentication of admin users.
2. The file realm has one and only one user (what the user name is does not matter).
3. That one user has no password.
By default, all of these conditions are true, unless you have created the domain with a specific user name and password. Thus, by default, the only administration user is admin with no password. If #3 is not true, you will need to specify the password. If #2 is not true, you will also need to specify the user name. If #1 is not true, you will need to specify the user name and password.
Use the login subcommand in local mode to authenticate yourself (log in to) a specific domain. After such login, you do not need to specify the administration user or password for subsequent operations on the domain. The login subcommand can only be used to specify the administration password. For other passwords that remote subcommands require, use the --passwordfile option, or specify the password at the command prompt. You are always prompted for the administration user name and password.
There is no logout subcommand. If you want to log in to another domain, invoke asadmin login with new values for --host and --port.
Determine the name of the domain that you are logging in to.
To list the existing domains:
Log in to the domain by using the login(1)command.
This example logs into a domain located on another machine. Options are specified before the login subcommand.
asadmin> --host foo --port 8282 login Please enter the admin user name>admin Please enter the admin password> Trying to authenticate for administration of server at host [foo] and port  ... Login information relevant to admin user name [admin] for host [foo] and admin port  stored at [/.asadminpass] successfully. Make sure that this file remains protected. Information stored in this file will be used by asadmin commands to manage associated domain.
This example logs into a domain on myhost on the default port. Options are specified before the login subcommand.
asadmin> --host myhost login Please enter the admin user name>admin Please enter the admin password> Trying to authenticate for administration of server at host [myhost] and port  ... An entry for login exists for host [myhost] and port , probably from an earlier login operation. Do you want to overwrite this entry (y/n)?y Login information relevant to admin user name [admin] for host [myhost] and admin port  stored at [/home/joe/.asadminpass] successfully. Make sure that this file remains protected. Information stored in this file will be used by asadmin commands to manage associated domain.
You can also view the full syntax and options of the subcommand by typing asadmin help login at the command line. For additional information about passwords, see Administering Passwords.
