+
+ Note that this module also provides authentication and password

+ module.
+
+ see
+ http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/kernextc/sec_load_mod.htm
+ for some information in the interface that this module implements
+
+ Many thanks to Julianne Haugh for explaining some of the finer
+ details of this interface.
+
+ To debug this module use uess_test.c (which you can get from tridge)
+ or set "options=debug" in /usr/lib/security/methods.cfg
