I'm using glauth with postgres plugin and I see that there's no way to change objectClass in my database (there's no any fields like this)

I've tried to launch glauth using backend="config"; added objectClass = person in [[users]] section and got error
ERRO 001 "error"="Near line 55 (last key parsed 'users.objectClass'): expected value but found \"person\" instead" "msg"="Configuration file error"

Is there any possibility to change objectClass?
