Oracle Solaris 10. UX: userdel: ERROR: Inconsistent password files. See pwconv(1M).

There is something wrong with user deleting in solaris 10, 
while you want to delete or add user, , and now you are getting following persist errors:

On USERADD : UX: userdel / useradd: ERROR: Inconsistent password files. See pwconv(1M).

Cause : in case you did manual delete entry in /etc/passwd? or something in like that way progress. 

Solution : Just make sure to remove lines relative to user you want to recreate in following files .
- /etc/opasswd
- /etc/oshadow
- /etc/passwd
- /etc/shadow
- /etc/user_attr

And remember that you should not leave blank lines in this files!!!
