Serv-U contains options which you can use to customize how Serv-U can be used, and which also provide ways to apply limits and custom settings to users, groups, domains, and the server in its entirety. The limits stack intelligently, with user settings overriding group settings, group settings overriding domain settings, and domain settings overriding server settings. In addition, limits can be applied only during certain days of the week or times of the day. It is possible to grant exceptions to administrators and restrict specific users more than others, providing total control over the server. The limits and settings in Serv-U consist of the following categories:
To apply a limit, select the appropriate category, click Add, select the limit, and then select or enter the value. For example, to disable the Lock users in home directory option for a domain, follow these steps:
The limits list displays the current limits applied to the domain. Limits with a light-blue background are default values. Limits with a white background are values that override the defaults. After completing the previous steps, a new Lock users in home directory limit appears in the list that displays "No" as the value. Because of inheritance rules, this option applies to all users in the domain unless overridden at the group or user level. For more information about this method of inheritance, see User interface conventions.
You can delete limits by selecting them and clicking Delete. To edit an overridden value, select the limit, and then click Edit. Default rules cannot be edited or deleted. Create a new limit to override a default one.
To create a limit that is restricted to a specific time of day or days of the week, click Advanced in the New Limit or Edit Limit window. Select Apply limit only at this time of day to specify a start and stop time for the new limit. To restrict the limit to certain days of the week, deselect the days for which you do not want to apply the limit. When a limit is restricted in this way, default values (or the value of other limit overrides) are applied when the time of day or day of the week restrictions are not met for this limit.
