Force LDAP group mapping synchronization

Hi,

LDAP group mappings working as expected and are updated when a user logs in, as far as i understood.

Since cookies are used and users normally log in once a month or more rarely, groups are almost never up-to-date.

Is there a way to force an update of a group-mapping as if a user logs out and in again? By the (Hub-)API or such, to run it once a day or when necessary?

If not: How do you manage LDAP-groups, when Youtrack doesn't notice your central data authority changing?
