CVM

The cvm-chain Module

Synopsis:

multi-module chaining shim

Credentials:

This module passes all its input credentials to the configured client modules

Description:

This module invokes a sequence of other modules. If the first module returns success (no error), the module passes the results back to its caller, otherwise it calls the second module and so on. If no module succeeds, the error code from the last module is returned.

Configuration Variables:

$CVM_CHAIN0 through $CVM_CHAIN9
These 10 variables specify the modules to be called. They are called in order from 0 through 9, if set.

Note: The previous versions of this module (not part of the main cvm package) used the environment variable $CVM_CHAIN to configure the list of modules. This will not work with this module. If you were using one of these previous versions you will need to change your configuration to match the above usage.
