NAME

       globus-k5 - Acquire Kerberos Credentials for use with Grid Services

SYNOPSIS

       globus-k5 SERVICE-COMMAND [SERVICE-ARGS...]

DESCRIPTION

       The globus-k5 program is an authorization module used by the globus-gatekeeper program to
       acquire Kerberos 5 Credentials prior to executing a Grid Service. This may be accomplished
       by running kinit with a password stored in the globuskmap file, using the NCSA krb525
       command, or the sslk5 command to use the X509 user proxy.

       The arguments passed to globus-k5 will not be used by it, but will be passed onto the job
       manager. The first parameter must be the path to the Grid Service.

       It is expected that the environment will contain the variables GLOBUSID and USER for the
       Grid and local POSIX user identities. This program is normally run as root, and will call
       seteuid() prior to executing the Grid Service.

       The parameters to use and the mapping for the globus to K5 user are located in the
       globuskmap file.

FORMAT OF THE GLOBUSKMAP FILE

       The globuskmap file is a line-oriented file which each line containing a command to run to
       acquire Kerberos 5 credentials for a Grid identity. Each line consists of an
       optionally-quoted GLOBUSID value followed by a command-line for running a process to
       acquire a Kerberos credential. For example:

           "/O=Example/OU=Grid/CN=Joe User" /usr/afsws/bin/klog -principal juser -password mypasswd -cell infn.it

ENVIRONMENT

       If the following variables affect the execution of globus-k5:

       GLOBUSKMAP
           Path to the globuskmap file.

       USER
           POSIX username that the service will run as.

       KRB5CCNAME
           Path to a Kerberos credential cache.

       GLOBUS_ID
           Grid identity to generate Kerberos credentials for.

FILES

       /etc/globuskmap
           Default file mapping Grid identities to Kerberos 5 principals.
