can't login into debian with the account any mor.
 

My system is debian7.8,there are two accounts in it ,one is root one is debian7.
The command was runned yesterday.
rm -rf ///Trash://*
I found that only root can login into,the account debian7 can't.
userdel debian7
useradd debian7

The strange thing : i can't still login into debian7 after running the two commands.

userdel debian7
useradd debian7

Hmmm
 

After deleting the account and adding it, did you set a password for it?
Deleting the account also deleted the old security information.

1.I have set password for the new account name--debian7 .
2.how to deleted the old security information?By which command?

what exactly will this command do when run as root???
