What is the meaning of ReadAttribute line in owncloud.log

Hello,
In “owncloud.log” file, we found several message "ReadAttribute" as followings:

{ "REQID": "f6qA \ / aJmrBkYypacgCg \ /", "RemoteAddr": "192.168.30.4", "app", "user_ldap", "message": "ReadAttribute: cn = st09179 [test@gmail.com] or gal =, dc = ts, dc = eads, dc = lcl found "," level ": 0," time ":" 2016-09-15T08: 59: 58 + 00: 00 "," method ":" GET "," url ":" \ / cron.php "}

I want to know the interpretation of this line "ReadAttribute"

I want to know if the lines ReadAttribute show necessarily a user authentication, when user access to the owncloud website. Or, this message may be generated after another action.

Thank you in advance

Hi,

you can read through the ownCloud source code to understand what this "ReadAttribute" is doing.
