In “Create new user” dialog enter the following information:

• Full user name (e.g. John Smith)

• Login – user login (e.g. smith)

• Password

• Group(-s) user belongs to (the list of available groups is provided below user info. If the required group is absent you need to create a new one (see Create new user group)).

Then click “Create” button.

2.10.3. Setting permissions

NextGIS Web is resource based so each component (layer, group, service) is a resource. NextGIS Web provides extended settings for resource access permissions.

Permissions could be set during resource creation (see. Adding resources), or using resource update (see. Layer settings). To manage permissions use a “Permissions” tab in create/update resource dialog (see. Pic. 2.86.).

Pic. 2.86. Permissions tab for resource.

You can grant, revoke and update permissions using this tab. You can grant different permissions to a single resource for different users and/or groups. A dialog with permission item settings is presented on fig. Pic. 2.87..

Pic. 2.87. Permission item settings dialog.

A dialog has the following elements:

• Action

• Principal

• Permission

• Resource

• Propagate

Action defines the kind of the rule - allow or deny.

Note

By default everything is denied.

Principal - a user or a user group who is subject to a rule.

Permission - defines allowed or denied actions with the resource. There are the following available types of permissions:

• All resources: All permissions

• Resource: All permissions

• Resource: Manage children

• Resource: Change permissions

• Resource: Read

• Resource: Create

• Resource: Update

• Resource: Delete

• Service: All permissions

• Service: Connect

• Service: Configure

• Data structure: All permissions

• Data structure: Write

• Data structure: Read

• Connection: All permissions

• Connection: Write

• Connection: Read

• Connection: Connect

• Web map: All permissions

• Web map: Display

• Data: All permissions

• Data: Write

• Data: Read

• Metadata: All permissions

• Metadata: Write

• Metadata: Read

Resource - type of resource the rule created for. This setting is important for resource groups where it is required to grant permissions only to some types of resources. If there is no need to grant different permissions to different types of resources, select “All resources” for this setting.

Propagate checkbox defines if permission rules need to be applied to resources in sub-groups or not. Note, that setting permissions for lower level resource and propagating doesn’t cancel the need to set them for upward resources. For example, if you gave read access to a resource group that is contained by other groups, but you didn’t give appropriate permissions for higher level resources (up to root) the user will not get access to current resource group.

Permissions could be assigned to resources indirectly. For example permission “Web map: Display” could be assigned for a resource group and if a “Propagate” checkbox is checked this rule will be applied to every web map inside this resource group and inside all the subgroups.

Here is a description for available permission types.

All resources: All permissions - allows or denies any actions with resources.

Resource: All permissions - allows or denies any actions with resources excluding resource groups.

Resource: Manage children - allows or denies update of child resources settings.

Resource: Change permissions - allows or denies access permissions management for a resource.

Resource: Read - allows or denies reading of resources.

Resource: Create - allows or denies creation of resources.

Resource: Update - allows or denies modification of resources.

Resource: Delete - allows or denies deletion of resources.

Service: All permissions - allows or denies any actions with a service.

Service: Connect - allows or denies connections to a service.

Service: Configure - allows or denies modification of service setiings.

Data structure: All permissions - allows or denies any actions with data structure.

Data structure: Write - allows or denies modification of data structure.

Data structure: Read - allows or denies reading of the data structure.

Connection: All permissions - allows or denies any actions with connections.

Connection: Write - allows or denies modification of connections.

Connection: Read - allows or denies reading of connection parameters.

Connection: Connect - allows or denies usage of connection (defines if layers and data from the connection will be available for a user).

Web map: All permissions - allows or denies any actions with a web map.

Web map: Display - allows or denies display of a web map.

Data: All permissions - allows or denies any actions with data.

Data: Write - allows or denies data modification.

Data: Read - allows or denies reading of data.

Metadata: All permissions - allows or denies any actions with metadata.

Metadata: Write - allows or denies modification of metadata.

Metadata: Read - allows or denies reading of metadata.

When you assign rights to a particular resource take into account the rights of its constituent resources. For example to provide access to a WMS service you should grant the following permissions:

• Service: Connect - to a connection itself.

• Resource: Read - to all resources (vector and raster layers) published with WMS service.

• Data structure: Read - to all resources (vector and raster layers) published with WMS service.

• Data: Read - to all resources (vector and raster layers) published with WMS service.

If you have a complex system with several maps and different users who should work with these maps you can create user groups. You can assign different permissions to every group.

2.10.4. Example: Assigning permissions

2.10.4.1. Close a group for guests, open it for the user

Pic. 2.88. Settings for resourse group.

Pic. 2.89. Settings for root resource group.

You can also allow the user reading all higher resource groups as alternative.

2.10.4.2. Grant guest user resource display permission

Note

Guest users will be able to see administrative interface and view all folders excluding especially closed ones.

Pic. 2.90. Settings for root resource group.

Pic. 2.91. Settings for resourse group with maps.

Pic. 2.92. Settings for resource group with geodata.

2.10.4.3. Grant guest user web map display permission

Note

Guest users will be able to see only a web map and layers in a folder, other resources will be closed.

Pic. 2.93. Settings for root resource group.

Pic. 2.94. Settings for resourse group with maps.

Pic. 2.95. Settings for resource group with geodata.

2.10.5. Update user password

To update user password you can use administrative interface. To do it select “Control panel” (see Pic. 2.3.) in the main menu (see item 1 in Pic. 2.2.). In control panel (see Pic. 2.4.) select “List” option in “Users” block and click pencil icon near the user you want to update password for (see Pic. 2.100.). In opened window in “Password” field fill in a new password and click “Save” button.

Also there is an option to change user password using command line:

Warning

Setting a password using a command line is not safe.

env/bin/nextgisweb --config config.ini change_password user password
env/bin/nextgisweb --config config.ini change_password user password

2.10.6. Customization of NextGIS Web outlook

You can customize the look of NextGIS Web, including logos, backgrounds, header and buttons colors etc. To do it select “Control panel” (see Pic. 2.3.) in the main menu (see item 1 in Pic. 2.2.). In control panel (see Pic. 2.4.) select “Custom CSS” in “Settings” block. In opened tab enter your own CSS rules. They will be used throughout your Web GIS on all its pages.

ui.header-nav header__right {display:none;}

2.10.7.5. Remove identification window header

Identification window is a popup that is shown when you click on a feature on a Web map. This setting will hide it’s header and layer selector:

div.ngwPopup__content div div.dijitAlignTop,
div.ngwPopup__features span.ngwWebmapToolIdentify-controller {
    display: none;
}
