11.4Considerations

WASD offers a comprehensive and versatile authentication and authorization environment. A little too comprehensive, often leaving the new administrator wondering where to begin. The role of this chapter is to provide a starting place, especially for sources of authentication, along with some basic configurations. Authentication and Authorization of WASD Features and Facilities contains a detailed explanation of all aspects. All examples here assume a standard installation and environment.

Just to clarify. Authentication is the verification of a user's identity, usually through username/password credentials. Authorization is allowing a certain action to be applied to a particular path based on that identity.

Changes to the authorization configuration file can be validated at the command-line before reload or restart. This detects and reports any syntactical and configuration errors but of course cannot check the intent of the rules.

$ HTTPD /DO=AUTH=CHECK

If additional server startup qualifiers are required to enable specific authorization features then these must also be provided when checking. For example:

$ HTTPD /DO=AUTH=CHECK /SYSUAF /PROFILE

A server's currently loaded authorization rules may also be interrogated from the Server Administration menu (see Server Administration of WASD Features and Facilities).

11.1SYSUAF/Identifier Authentication

This setup allows any active account to authenticate using the local VMS username and password. By default not every account may authenticate this way, only those holding specified VMS rights identifiers. The examples provided in this section allows access to the WASD online Server Administration facility, and so may be followed specifically for that purpose, as well as serve as a general guide.

After Changes

If the WASD_CONFIG_AUTH configuration file is changed, or rights identifiers are granted or revoked from accounts, the server should be directed to reload the file and purge any cached authorization information.

$ HTTPD/DO=AUTH=LOAD $ HTTPD/DO=AUTH=PURGE

11.2Other Authentication

Other sources of authentication are available, either by themselves or used in the same configuration file (different realms and paths) as those already discussed (Authentication Sources of WASD Features and Facilities). Non-SYSUAF sources do not require any startup qualifier to be enabled.

11.3Read and Write Groupings

WASD allows separate sources for groups of usernames to control read and write access in a particular realm (Realm, Full-Access, Read-Only of WASD Features and Facilities).

These groups may be provided via simple lists, VMS identifiers, HTA databases and authorization agents. The following example shows an identifier authenticated realm with full and read-only access controlled by two simple lists. For the first path the world has no access, for the second read-only access (with the read-only grouping becoming basically redundant information).

["Realm Name"=identifier_name=id;full_access_name=list;read-only_name=list] /web/area/* r+w ; /web/another-area/* r+w ; r

11.4Considerations

Multiple authentication sources (realms) may be configured in the one WASD_CONFIG_AUTH file.

Multiple paths may be mapped against a single authentication source.

Any path may be mapped only once (for any single virtual service).

Paths may have additional access restrictions placed on them, including client host name, username, etc. (Access Restriction Keywords of WASD Features and Facilities).

The configuration file is loaded and stored by the server at startup. If changed it must be reloaded to take effect. This can be done manually using

$ HTTPD/DO=AUTH=LOAD

Authentication information is cached. Access subsequently removed or modified will not take effect until the entry expires, or is manually purged using

$ HTTPD/DO=AUTH=PURGE

Failed attempts to authenticate against a particular source are limited. When this is exceeded access is always denied. If this has happened the cache must be manually purged before a user can successfully authenticate

$ HTTPD/DO=AUTH=PURGE
