Plugin dialog could not be loaded

Hello Team,

I am trying to integrate JumpCloud on Mariadb for authentication purposes on centos7. I can easily connect  to the MariaDB server with my JumpCloud credentials through the terminal of the same server. But when I try to connect the server through "MySQL Workbench", it displays  a dialogue box with message " Plugin dialog could not be loaded: /usr//usr/lib/mysql/plugin/dialog.so: cannot open shared object file: No such file or directory".When I searched for 'dialog.so', it was found in "/usr//usr/lib64/mysql/plugin/". How can it be solved?
