\label{Domain_Configuration_Quotas}
By default, each user in your domain can create blogs, a personal
information page, and store files in an individual portfolio space.
Students can submit items from their portfolio to meet the requirements
of assignments in their courses.
You can choose to disable personal information pages, blogs and/or portfolios
for different groups of users defined for your domain (e.g., Faculty, Adjunct,
Staff, Student). If the ``Modify User'' utility in User Management is
used to explicitly set availability of these tools for a particular user,
that will override the corresponding settings determined by the user's
affiliation.
If you choose to enable portfolios, default quotas (in MB)
can similarly be set to vary by institutional affiliation.
If a user is affiliated with more than one group, whichever default
quota is largest for the different groups is the one which applies.
Institutional types are defined in the ``Institutional user types''
section on the ``Default authentication, language, timezone, portal, types''
screen. If no types have been defined, then a single default quota
will apply for all users from the domain.
Default portfolio quotas which can be set for users in your domain
will be overridden by any quota you set for an individual user via:
the ``Modify User'' utility.
Additional options for authoring spaces can be set for the various user
types: (a) whether webDAV is active, and (b) the default quota for Authoring Space.
These only come into effect for a particular user, when an author and/or one or
more co-author roles have been assigned to a user to provide access to one or more
Authoring Spaces.
WebDAV allows a user to connect to an Authoring Space in the same way as removable
media, and to use their own laptop/desktop computer's file management tools and
applications to move, edit and delete files. See: ``WebDAV access to Authoring Space''
section in the Authoring manual for more information.
Note: webDAV usage requires Apache with SSL to be running on the library server.
The user will be prompted to enter a username (this will be the LON-CAPA username
if the user is also the author, or username:domain of the user,
if the access is for a co-author), and the user's LON-CAPA password.
If you use Single Sign On to authenticate LON-CAPA users in your domain, then to
support webDAV you also need to support authentication by LON-CAPA for your users.
This can achieved if the authentication type stored internally for each SSO user is
set to either (a) Kerberos 5 (with a parameter -- the appropriate Kerberos realm
set), or (b) Local Authentication, with /home/httpd/lib/perl/localauth.pm
customized to verify username and password (e.g., via LDAP). If a user can log-in
to LON-CAPA via the URL /adm/login (thereby by-passing SSO), then the same user will
also be able to authenticate using a WebDAV client (assuming other requirements are
met, i.e., SSL, WebDAV access enabled, active author or co-author role).
The requirement to obsolete published files before moving or deleting them, which applies to
the regular web browser-based management of Authoring Space, also applies in the webDAV
environment. Moving and deleting directories in the webDAV environment is prohibited if
the directory, or any (nested) subdirectory contains a non-obsolete published resource.
Given the ability to easily delete unpublished content in webDAV (without the ability to
reverse the deletion), it is important that authors assigned webDAV access are especially
careful when working in the webDAV environment.
