If you would get “Failed to authenticate user.” error, there is no way to fix except restore or reinstall. And, If you reinstall unisphere you will loose performance database. There is a trick to not get this error.)

Security expolit on Netbackup (No.Restrictions)
Sometimes we or some consultants put No.Restrictions file in “INSTALL DIR\netbackup\db\altnames” directory, this option makes our work easier. But it is a security risk, because of every netbackup client on the your network can restore data from any other clients. So, anybody can restore data of your important servers, then they can lookup and/or copy your important datas. To close this security exploit, you must delete the file No.Restrictions.
EMC Networker security exploit that “Remote access”
If you didn’t care when you installed EMC networker software, some consultants enter an option *@* for every client, this means that every networker client on the your network can restore data from any other clients. So, anybody can restore data of your important servers, then they can lookup and/or copy your important datas.
