Adding crypt(3) salt format (ITS#1202)

Submission from: (NULL) (

See this thread:

But here's the gist of it anyway:
>Other than to use adaptive code (such as code which calls
>crypt_get_format(3) or like functions) [which is likely a rat
>hole], a single configuration option might resolve this.
>        crypt-salt-format "%.2s"
>        crypt-salt-format "%.8s"        (default)
>        crypt-salt-format "_abcd%.4s"
>        crypt-salt-format "$1$%.8s"
>I suggest a quick hack initially.  Add a static (local to file)
>variable to liblutil/passwd.c which holds a point to a format
>string (default to NULL) and then code to check if the generate
>crypt() password function.  If NULL, do what we do today.  Otherwise,
>generate a 16 character long, base64 salt string and snprintf it
>into the salt to be passed to crypt using the specified format.  And
>an access function which sets the static variable.
>In slapd, hack config.c to have an directive which sets the
>format via an access function.
