PAM_WRAPPER(1) PAM_WRAPPER(1) NAME pam_wrapper - A preloadable wrapper to test PAM applications and PAM Mod- ules SYNOPSIS LD_PRELOAD=libpam_wrapper.so PAM_WRAPPER=1 PAM_WRAPPER_SER- VICE_DIR=/path_to_config ./myapplication DESCRIPTION This tool allows you to either test your PAM application or module. For testing PAM applications we have written a simple PAM module called pam_ma- trix (see below). If you plan to test a PAM module you can use the pamtest library we have implemented. It simplifies testing of modules. You can be combine it with the cmocka unit testing framework or you can use the pro- vided Python bindings to write tests for your module in Python. ENVIRONMENT VARIABLES pam_wrapper is activated and controlled by environment variables. You can set the following variables: PAM_WRAPPER If you load the pam_wrapper and enable it with setting PAM_WRAPPER=1 all PAM calls will be wrapped so you are able to specify a directory with the service files pam_wrapper should be using. PAM_WRAPPER_SERVICE_DIR The directory to read PAM service files from. If you want to use pam_matrix (see below) or want to test your own PAM mod- ule you need to specify the absolute path to your module in the service files. PAM_WRAPPER_DEBUGLEVEL If you need to see what is going on in pam_wrapper itself or try to find a bug, you can enable logging support in pam_wrapper if you built it with debug symbols. * 0 = ERROR * 1 = WARNING * 2 = DEBUG * 3 = TRACE PAM_WRAPPER_USE_SYSLOG By default pam logs will go to the pam_wrapper DEBUG log level and will not be sent to the syslog. If you want to log to the syslog to you can set this variable to 1. PAM_WRAPPER_KEEP_DIR If this option is set to 1, then pam_wrapper won't delete its temporary directories. Mostly useful for pam_wrapper development. PAM_WRAPPER_DISABLE_DEEPBIND This allows you to disable deep binding in pam_wrapper. This is useful for running valgrind tools or sanitizers like (address, undefined, thread). EXAMPLE A service file for pam_wrapper should look like this: auth required /usr/lib/pam_wrapper/pam_matrix.so passdb=/path/to/pdb account required /usr/lib/pam_wrapper/pam_matrix.so passdb=/path/to/pdb password required /usr/lib/pam_wrapper/pam_matrix.so passdb=/path/to/pdb session required /usr/lib/pam_wrapper/pam_matrix.so passdb=/path/to/pdb The name of the file should represent the service name used by your PAM ap- plication. LD_PRELOAD=./libpam_wrapper.so PAM_WRAPPER=1 PAM_WRAPPER_SER- VICE_DIR=./pam_services ./my_pam_app PAM_MATRIX We offer a module to make testing of PAM applications easier. You find more information in the pam_matrix(8) manpage. AUTHOR The Samba Team Author. 2020-01-31 PAM_WRAPPER(1)
