SIGNON System Task Usage

Signing off the current user

You can use the SIGNON task at a terminal without first signing off the current user (if any). In this case, SIGNON automatically signs off the original user.

Supplying your password

You can specify your password along with or after entering your user ID:

• If your password is not confidential, you can enter it along with your user ID on the same line. Your password is displayed when you type it. For example:

Vnnn ENTER NEXT TASK CODE:      CA IDMS release nn.n tape volser node nodename
 signon user1 allpass

• If your password is confidential, enter your password after you have typed your user ID and pressed Enter. DC/UCF prompts you to type the password. Your password is not displayed on the screen when you type it.

How DC/UCF processes signon requests

When you enter the SIGNON task, DC/UCF:

1. Accesses the security system to:
   • Determine your authority to sign on to the system
   • Validate your password

   Users are defined in the DDLSEC area.

2. Builds a signon element (SON) for you based on information returned from the security system.

   A SON is built for you when you successfully execute the SIGNON task. Until that time, your signon is unknown to DC/UCF because no SON exists for you; you can execute only tasks and programs that have been authorized for public use.

3. Builds a session profile based on your system and user profiles.
4. Executes your signon CLIST if one was specified as a profile attribute.

Supplying a new password

If you want to change your password, you must specify both the old password and the new password, then follow the prompts to complete the change.

Example

In this example, user LRL1 signs on to DC/UCF and specifies a password:

• Input:

Vnnn ENTER NEXT TASK CODE:      CA IDMS release nn.n tape volser node nodename
 signon lrl1 mypass

• Result:

Vnnn ENTER NEXT TASK CODE:      CA IDMS release nn.n tape volser node nodename
 IDMS DC258003 V55 USER LRL1 SIGNED ON LTERM VL07004 AT 13:29:39.83 99.013
