Bug#729813: jessie/testing pam_unix2 (2.6-1) module is compiled without blowfish support

[Michael Ablassmeier <abi@grinser.de>]

hi there,

i think this happens because of:

 checking for xcrypt_gensalt_r... no

checking the source reads:

#if defined(HAVE_XCRYPT_GENSALT_R)
    [ do stuff ]
#else
      __write_message (pamh, flags, PAM_ERROR_MSG,
               _("No support for blowfish included"));

I guess md5 is broken aswell, see this bugreport against the ubuntu
package:

 https://bugs.launchpad.net/ubuntu/+source/libpam-unix2/+bug/372406

looking at the web it seems like the original source of the package at suse is
not available anymore, it may also be unmaintained. I wasnt able to find any
recent repositories.

Should however should be fixable using 

 xcrypt_gensalt_rn

instead of the xcrypt_gensalt_r.

bye,
    - michael
