UCTL_ACCESS - UCTL UACL entry
Description
A UCTL_ACCESS UACL entry either allows or denies access to Universal Control Server services.
If access is permitted, UCTL_ACCESS also specifies whether or not user authentication is required.
There are two forms of the UCTL_ACCESS entry based on the client identification method:
- uctl_access form is for IP-based client identification.
- uctl_cert_access is for X.509 certificate-based client identification.
A uctl_access UACL entry is matched if all of the following occur:
- Request comes from an IP address identified by host.
- Remote end is executing as user remote_user.
- Remote user is requesting to execute a command as local user local_user.
A uctl_cert_access UACL entry is matched if both of the following occur:
- Request comes from a client with a certificate identifier of certid.
- Remote user is requesting to execute a command as local user local_user.
The first matching rule is used to control access.
See Universal Access Control List (UACL) for details on host, remote_user, local_user, and certid specification syntax.

Values
Valid values for access are:
- deny
Service is denied. A message is returned to the remote end. The connection is closed. - allow
Service is accepted and processed.
Valid values for auth are:
- auth
Local user account must be authenticated. The Manager must provide a proper password for the account. - noauth
User ID provided by the Manager does not have to match the user process being stopped.
IBM i, UNIX, z/OS
Additionally, noauth specifies that the local user account does not require user authentication. The Manager still must supply a password to satisfy command syntax rules, but it will not be verified. Any password value will suffice.
Windows
To set noauth via the Universal Configuration Manager, de-select Require matching local user account when you are adding or editing an Access ACL (uctl_access) entry.
Note
noauth should be used with care. Turning off user authentication may violate your local security policies on the Server system.
