 - Run the following command to get the list of the IP addresses where the login attempts are coming from (change the date in search if mandatory)

# cd /var/log/brs/zuul
# zgrep -i 'login' zuul.2024-* | awk -F remoteHost '{ print $2 }' | sort | uniq -c
   3683  10.4.157.200, uri /api/v2/login
    763  10.4.128.200, uri /api/v2/login
    190  127.0.57.200, uri /api/v2/login

• The admin account locked because there are too many attempts from a certain IP address which corresponds to the DPA IP address.
• In DPA, there is a credential created for connection to PowerProtect Data Manager. In this case, it's "admin" with the same password. That password has been changed, but not updated in DPA. That credential in DPA must be updated with the correct password.

• In DPA UI, navigate to System Settings > Credentials…edit the one used for PPDM connection and update the password. 
• If you are using the credentials for username and password in PowerProtect Data Manager UI login and the same for DPA logins. It is recommended to create a new credential for the DPA logins so it wont affect the PowerProtect Data Manager UI logins.  To do so, please refer to the relevant Data Protection Advisor documentation.
