When a user is added to linux, the Current Kerberos password 1 is displayed. When a user is added to linux, the user group is specified for the user, add the user to the sudo user group shell> useradd user. You can also use shell> adduser user to use adduser. In this way, the system automatically creates the standme directory, then you are prompted to set the password. If useradd is used, passwd user is also required to set the password. Previously, when debian 5 was used, it was okay to directly add the user and set the password. After debian squeeze 6.0 was completely installed, an error occurred in www.2cto.com shell> sudo passwd userCurrent Kerberos password: passwd: user not known to the underlying authentication modulepasswd, I found that I don't know how to disable it, So I simply unmount the aptitude purge libpam-krb5 and add the user directly, it's okay.
