Hi Chris, authconfig --enable-shadow --enablemd5 should get redhat doing what you're after, otherwise, man authconfig should help. You will always get a different hash value for the password, whenever it is reset. The algorithm is one-way, and seed dependent. I've never done this between distros... maybe you should look into centralising authentication using an ldap depository...? (: Now that would keep you off the streets for a while! Is your network big enough to warrant it? Could be a fun joint CLUG project? As ever, $0.02 Steve
