Master_SSL_CA_Path does not work

Following the directions in https://mariadb.com/kb/en/library/replication-with-secure-connections/, after generating keys following the tutorial at https://www.cyberciti.biz/faq/how-to-setup-mariadb-ssl-and-secure-connections-from-clients/ linked from https://mariadb.com/kb/en/library/secure-connections-overview/, results in an error.

Specifically:

CHANGE MASTER TO

  MASTER_HOST='master_host_name',

  MASTER_USER='user_name',

  MASTER_PASSWORD='password',

  MASTER_SSL=1,

  MASTER_SSL_CA = 'ca_file_name',

  MASTER_SSL_CAPATH = 'ca_directory_name',

  MASTER_SSL_CERT = 'cert_file_name',

  MASTER_SSL_KEY = 'key_file_name';

is misleading, because the variable MASTER_SSL_CAPATH does nothing in 10.2.11

MASTER_SSL_CA, MASTER_SSL_CERT, and MASTER_SSL_KEY must contain full path names for each corresponding file, and changing the value of MASTER_SSL_CAPATH has no effect on these variables. When the filenames are not fully qualified, turning on replication results in

Last_IO_Error: error connecting to master 'repl@10.0.0.1:3306' - retry-time: 10  maximum-retries: 86400
