Installation

LCAS uses the globus security libraries (gss, gsi, openssl), which are provided by e.g. VDT (Virtual Data Toolkit), the GACL libraries, and the VOMS API. These libraries in addition to the libraries listed here , have to be installed on the CE.

Table 1: RPMs to be installed.

The LCAS library will be installed in /opt/edg/lib/lcas/ and the example configuration files in /opt/edg/etc/lcas/. The authorization modules and example authorization plugin will be installed in the modules subdirectory of the directory where the LCAS library is installed.

The path of the modified gatekeeper executable will be /opt/edg/sbin/edg-gatekeeper.

From CVS:
The LCAS library can also be built directly from the cvs repository by the following steps:

• cvs export -r <version_tag> fabric_mgt/gridification/lcas - export the source from CVS using a tagged version (e.g. v1_1_2)
• cd fabric_mgt/gridification/lcas; ./autogen.sh - run the bootstrap script to run autotools
• ./configure -prefix=<path> -libdir=<path>/lib/lcas
  -includedir=<path>/include/lcas -sysconfdir=<path>/etc/lcas - run the configure script
• make rpm - if you want to make the rpm
• make; make install - build and install the LCAS Library and the example configuration
• make apidoc - if you want to create the API documentation. This is useful for developers of new authorization plugins.
