 The sudo package for 7.1 used the system-auth facility of newer pam
 versions and thus would not install or work correctly under Linux-
 Mandrake 7.1.  This update resolves the dependancy issue as well as

Please verify the update prior to upgrading to ensure the integrity of

  rpm --checksig package.rpm
You can get the GPG public key of the Linux-Mandrake Security Team at
If you use MandrakeUpdate, the verification of md5 checksum and GPG
signature is performed automatically for you.
