Description Miloslav Trmač 2009-02-26 22:36:28 UTC 
Version-Release number of selected component (if applicable):
yptools-2.9-4

Upstream yppasswd only creates DES-hashed passwords, yppasswd in Fedora creates a md5 password if the original used md5.  Please extend this to support SHA-2 passwords, per http://people.redhat.com/drepper/SHA-crypt.txt .  (The             "passwdlen = 13 + strspn(pwd->pw_passwd + 13, ...)" truncation will also have to be modified, because the salt in SHA-2 can have 16 characters, and be preceded with $5$rounds=999999999$.)
