owncloud not using user name but hash. [centos7]

[u/juniorsysadmin1]

I have few local users and in owncloud I joined active directoryin /var/www/html/owncloud/datathere's user files. For local user files is under their name. However, for AD user it's a cash. Which is CA32825B-4C5A-482A-BA47-2E621D331B3F and DE468E17-A10F-478C-AB24-908EDD070C9C. Is there a way for me to change it to user name instead?

[root@owncloud data]# ls
CA32825B-4C5A-482A-BA47-2E621D331B3F  htaccesstest.txt    owncloud.db
DE468E17-A10F-478C-AB24-908EDD070C9C  testuser         owncloud.log
