dovecot - Sep 2019 - New to dovecot admin, question about using LDAP for user-specific values

I am new to dovecot administration. I?ve read the Wiki but that hasn?t given me
the understanding I need.

When I query my LDAP (on macOS) on a value for user ?gerben?, I can get that:

dumbledore:~ gerben$ dscl /LDAPv3/127.0.0.1 -read /users/gerben GeneratedUID
GeneratedUID: 780D870E-6B00-478E-AB70-3D3307215A82

I would like to use that value in dovecot settings, e.g. something like

user_attrs = \
  =mail=maildir://Library/Server/Mail/Data/mail/%{ldap:GeneratedUID}

Is this possible and if so what do I exactly need to do to get this working?

As the answer is in the question, it is hard to give you any hint about what
should be done.

What is wrong with 

user_attrs = \
  =mail=maildir://Library/Server/Mail/Data/mail/%{ldap:GeneratedUID}
<maildir://Library/Server/Mail/Data/mail/%25%7Bldap:GeneratedUID%7D>

Did you try it ? Have you got any issue with it ?
