-LEGACY CRYPT
-============
-
-There are two crypt types that are disabled by default: bigcrypt and broken md5_crypt.
-They are disabled because they use static buffers which is bad when doing PAM authentication using this module in a multithreaded server.
-All the other crypt types are checked via the systems crypt_r function if available, else with the normal crypt function and the same static-buffer-problem.
-
-bigcrypt was used on DEC systems to allow for longer passwords.
-You can check if your passwd file contains any of these with `cut -d: -f2 passwd-file | egrep '^[^$].{13}'`.
-
-Broken md5_crypt is a speciality of big-endian systems.
-An early implementation of md5_crypt got the byte order wrong here and produced different crypt outputs.
-You might have some of these crypt hashes in your passwd file only if you created them on a big-endian system.
-If an md5_crypt hash also worked on a little-endian system (up to and including libpam-pwdfile 0.99) it isn't broken md5_crypt.
