|
*
|
|
* @brief Description of the krb5_aname_to_lname(3) plugin facility.
|
|
*
|
|
* The krb5_aname_to_lname(3) function is pluggable. The plugin is
|
|
* named KRB5_PLUGIN_AN2LN ("an2ln"), with a single minor version,
|
|
* KRB5_PLUGIN_AN2LN_VERSION_0 (0).
|
|
*
|
|
* The plugin for krb5_aname_to_lname(3) consists of a data symbol
|
|
* referencing a structure of type krb5plugin_an2ln_ftable, with four
|
|
* fields:
|
|
*
|
|
* @param init Plugin initialization function (see krb5-plugin(7))
|
|
*
|
|
* @param minor_version The plugin minor version number (0)
|
|
*
|
|
* @param fini Plugin finalization function
|
|
*
|
|
* @param an2ln Plugin aname_to_lname function
|
|
*
|
|
* The an2ln field is the plugin entry point that performs the
|
|
* traditional aname_to_lname operation however the plugin desires. It
|
|
* is invoked in no particular order relative to other an2ln plugins,
|
|
* but it has a 'rule' argument that indicates which plugin is intended
|
|
* to act on the rule. The plugin an2ln function must return
|
|
* KRB5_PLUGIN_NO_HANDLE if the rule is not applicable to it.
|
|
*
|
|
* The plugin an2ln function has the following arguments, in this order:
|
|
*
|
|
* -# plug_ctx, the context value output by the plugin's init function
|
|
* -# context, a krb5_context
|
|
* -# rule, the aname_to_lname rule being evaluated (from krb5.conf(5))
|
|
* -# aname, the krb5_principal to be mapped to an lname
|
|
* -# set_res_f, a function the plugin must call to set its result
|
|
* -# set_res_ctx, the first argument to set_res_f (the second is the result lname string)
|
|
*
|
|
* @ingroup krb5_support
