29 To install this module copy nsswitch/WINBIND to /usr/lib/security and add
30 "WINBIND" in /usr/lib/security/methods.cfg and /etc/security/user
31
32 Note that this module also provides authentication and password
33 changing routines, so you do not need to install the winbind PAM
34 module.
35
36 see
37 http://publib16.boulder.ibm.com/doc_link/en_US/a_doc_lib/aixprggd/kernextc/sec_load_mod.htm
38 for some information in the interface that this module implements
39
40 Many thanks to Julianne Haugh for explaining some of the finer
41 details of this interface.
42
43 To debug this module use uess_test.c (which you can get from tridge)
44 or set "options=debug" in /usr/lib/security/methods.cfg
