# Setting initial access to all global permissions

In a self-hosted instance of Tonic Textual, the default global permission set for Textual users does not include the ability to manage or assign global permissions.

Until you set the initial access to all global permissions, there is no way to manage or assign global permissions.

To set the initial access to all global permissions, you set the list of users or groups as the value of the [environment variable](/textual/textual-install-administer/configuring-textual/textual-env-var-configure.md) `SOLAR_ADMINISTRATORS`.

The users and groups are assigned the built-in Admin (Environment) permission set.

From the **Global Permission Sets** list:

* You cannot revoke the built-in Admin (Environment) permission set from those users or groups.
* You cannot assign the Admin (Environment) permission set to other users or groups.

To change the assigned users and groups, you update the value of `SOLAR_ADMINISTRATORS`.
