Due to several and frequent attempts from Avamar with an incorrect DD Boost password, the account gets locked, closing all the connections to the Avamar. Attempting an SSH connection to the Data Domain as the DD Boost user shows that the account is locked due to X failed logins: admin@avamar:~/>: ssh ddboost@datadomain EMC Data Domain Virtual Edition Account locked due to X failed logins Password: From a Data Domain account, the output of the below command shows the DD Boost user as enabled: sysadmin@ddve# user show list User list from node "localhost".
