Breaking change for queries used in definition query obligations (since 4.21.1)

Policies allow to define definition query obligations to limit access to features of a layer. Definition query obligations require you to define a query that may contain references to attributes of the requesting user like this:

Referencing the user attribute 'customattribute0' in a query
LEVEL <= ${user.customattribute0}

security.manager now checks that user attributes only resolve to SQL literal values when they are replaced in query expressions. By default, non-literal values are rejected and will cause a request failure.

If you have to accept user attribute values resolving to anything else than SQL literals, you must now explicitly mark them as insecure inside the query. Otherwise user requests will fail with errors. The following example demonstrates how to flag a user attribute that should be replaced with the provided value without any checks.

Accepting any kind of user attribute value
LEVEL <= ${user.customattribute0;insecure}

Deprecated Features

The following features are regarded as deprecated and might be removed in future:

  • Native WSS authentication protocol of the Web Security Service (WSS) component

  • (Json) Token authentication protocol of the Web Security Service (WSS) component. It is recommended to use the - currently named - "agstoken" authentication protocol instead.

  • Protection of Web Coverage Service (WCS)

  • Protection of transactional WFS (WFS-T)

  • INSPIRE View and Download Services as separate service types are maintained within the service types WMS and WFS

  • Access to protected services via Gateway application (tab "Gates" in the security.manager administration)

  • Protection of ArcGIS Server services

Known Limitations

The following list contains all limitation known at the time of the release of version 4.21.

Delayed visibility of parallel changes of users and rights by different users or external systems (eg LDAP clients) in the security.manager Administrator

To visualize changes from other users / systems in the tree displayed on the left side of the Administrator interface, simply select the root node of the tree and the reload tree button.

Evaluation of two rights

When two rights are defined that are applicable to a user, it is important to determine the correct sequence in the Security Manager administrator (in the dialog "Policy Set"). For example: It is a legal definition that all users are granted access to a WMS, but with copyright restrictions. A user might be a member of a user group "registered" where another piece of legislation for this WMS defines that the access granted WITHOUT Copyright constraint. Both of these rights are valid if the user group "registered" accesses the WMS. In this case, the first policy in the list is used. To prevent the users of the group "registered" from seeing the same copyright notice as unregistered users, this right must be uppermost in the administration set.

WFS feature types are required to have unique names

The security.manager does not distinguish feature types which have the same name but different namespaces, for example x:city is recognized as equal to y:city. Therefore It is required that feature types have unique names.

Use of variable feature IDs in WFS services as a source of spatial conditions

Care must be taken of the accuracy and stability of the displayed feature IDs when using them to create spatial obligations. Feature IDs of the form fid-4d0f905b_126c17decf6_-7d52 indicate internal auto-generated feature-IDs, which change with each new request and thus can not be used for referencing features. If feature IDs change with each request to the WFS, this is due to a lack of feature IDs in the WFS response. The configuration of the WFS service needs to be reviewed so that stable feature identifiers are delivered correctly.

If installed in an instance of Tomcat which does not yet contain the directory [TOMCAT_HOME]/conf/Catalina/localhost, some configuration files are not created correctly

Alternative 1: Create the folder prior to installation.

Alternative 2: During an installation, the context.xml files are stored in the [SECMAN_INSTALL]/postinstall directory. They can be simply copied into the directory [TOMCAT_HOME]/conf/Catalina/localhost. In the installation type container-managed database, the xml files with the suffix -jndi.xml need to be copied.

The following files must be copied:

  • administration.xml

  • gateway.xml

  • wss.xml

Use of unofficial EPSG codes by ArcGIS Server services

Depending on their configuration, ArcGIS Server services sometimes use unofficial EPSG codes for Gauß-Krüger reference systems. These are internally mapped to the corresponding official EPSG codes, The following mappings are used:

  • EPSG:31492 → EPSG:31466

  • EPSG:31493 → EPSG:31467

  • EPSG:31494 → EPSG:31468

  • EPSG:31495 → EPSG:31469

This mapping is only applied to protected services. For the definition of spatial restrictions via a WFS, only official EPSG codes are supported.

Problem with spatial restrictions for ArcGIS Server WFS

ArcGIS Server WFS do not support multipolygons or more than one polygon within a spatial filter. Thus, spatial restrictions cannot be applied if more than one geometry are selected for this restriction or if the incoming request already contains a spatial filter.

When using a Safari browser, repeated logins might be required. To avoid this, change the security settings to always accept cookies.

Limitation regarding Spatial Obligations for "tiled" ArcGIS Server MapServer

Support for spatial obligations with ArcGIS Server cached MapServer instances requires to use the cache storage format "Compact". If any other storage format is used spatial obligations are ignored.

WMS GetMap requests with SLD parameter blocked if layerDefs parameter would be applied

As described in "Filtering features using the layerDefs parameter in WMS requests" , layerDefs has a lower priority when SLD or SLD-BODY parameter is present and is ignored.

Printing of secured services only possible with ags-relay URLs

URLs of secured MapServer services have to be used with ags-relay URL schema:

http://[HOST]/wss/service/ags-relay/
  [EndpointID]/[AUTH_SCHEME]/arcgis/rest/services/
  [SERVICENAME]/MapService

HTTP chunked transfer encoding must be disabled in security.manager when securing ArcGIS geocoder

The ArcGIS Geocoding Server does not support HTTP chunked transfer encoding. If you want to secure that service, chunked encoding must be manually disabled in the settings file of security.manager. To do that, make sure that the property http.client.chunking in the application.properties file is set to false (SECMAN-658).

Spatial Obligations are not supported for INSPIRE Feature Download Services based on ArcGIS for INSPIRE

ArcGIS for INSPIRE Feature Download Services do not support Polygons in queries with spatial filters. Hence for a spatial restriction is not possible.

Invalid responses from INSPIRE Feature Download Services based on ArcGIS for INSPIRE with stored queries

ArcGIS for INSPIRE Feature Download Services might create invalid responses if a GetFeature request references multiple stored queries or contains multiple query elements.

ArcGIS Server WFS and spatial restrictions as well as OGC Filter Expressions

Access to protected ArcGIS Server-based WFS might fail when spatial obligations or OGC Filter Expression obligations are in play. Affected are ArcGIS Server versions 10.3 and higher, which don’t properly support the OGC specifications. Depending on the WFS versions requested by the client (1.0.0, 1.1.0, 2.0.0) you might encounter different error messages.

UMN MapServer WFS and spatial obligations as well as OGC Filter Expressions

The WFS 1.0.0 and 1.1.0 implementations of UMN MapServer do not support the GML versions as stated in the specifications. Because of this spatial obligations and obligations with OGC Filter Expressions are not supported.

ArcGIS Server WFS and DescribeFeatureType requests

For ArcGIS Server WFS services, DescribeFeatureType requests without listing actual FeatureTypes might lead to exceptions, if this WFS provides many FeatureTypes, or the FeatureTypes have long names.

Performance and protected services with huge number of resources

If a protected service (for example a map service) contains a huge number (> 60) of resources (for example layers) performance of service requests decreases noticeably. Consider splitting up such mapping services into several services.

HTTP Basic Authentication in ArcMap and ArcGIS Pro

When trying to load a protected service into ArcMap or ArcGIS Pro via httpauth login fails although correct credentials were specified if username or password contain non-ASCII characters like german umlauts.

ArcGIS Webadaptor with name "rest" or "services"

When the webadaptor for ArcGIS Server is named "rest" or "services" like http://[HOST]/rest/rest/services or http://[HOST]/services/rest/services, the ArcGIS Server cannot be protected by security.manager. When named "rest", no policies can be created, when named "services" policies cannot be enforced.

ArcGIS Server MapServer /find operation with large result sets and spatial obligations

In combination with spatial obligations, the MapServer /find operation may not return all expected features. Large result sets of the /find operation will be capped if they exceed the server side limit of features to return. Spatial obligations will only be applied to the capped result set.
