-// sshd_test_pw.c
-// Wrapper to inject test password data for sshd PAM authentication
-//
-// This wrapper implements custom versions of getpwnam, getpwnam_r,
-// getspnam and getspnam_r. These functions first call their real
-// libc versions, then check if the requested user matches test user
-// specified in env variable TEST_USER and if so replace the password
-// with crypted() value of TEST_PASSWD env variable.
-//
-// Compile:
-// gcc -Wall -shared -o sshd_test_pw.so -fPIC sshd_test_pw.c
-//
-// Compile with debug:
-// gcc -DVERBOSE -Wall -shared -o sshd_test_pw.so -fPIC sshd_test_pw.c
-//
-// Run sshd:
-// LD_PRELOAD="sshd_test_pw.so" TEST_USER="..." TEST_PASSWD="..." sshd ...
