Sorry for that! I was offline during writing my answer to your mail and so it left my outbox after the advice from Sami.
The solution works well when using passwd userdbs only. I didn’t get it running in conjunction with ldap userdb. I tried to use an LDAP attribute and mapping it to userdb_acl_globals_only and another try with acl_globals_only. Both attributes were not considered by the lookup. Another try was to use a separate passwd-userdb for this attribute only. When placing the passwd-userdb before the ldap-userdb the ldap attributes are not considered. If the ldap-userdb is placed before the passwd-userdb, the extra attribute is not considered. I think this is a wanted behaviour.
Any ideas in conjunction with LDAP?

As Sami pointed out, I had wrong syntax:
close, but few typos. userdb should be:
userdb { driver = passwd-file args = username_format=%Lu /etc/dovecot/share.passwd }
