Grafana ldap authentication problem

We are doing ldap authentication with grafana.
We can login with organization ID, however we are not able to access the dashboards created by userA (orgaA) when re-login with userA.


You can only see dashboards for the current active org you are using, switch org via the profile page or profile sidemenu

When I log off and login again, I cant see the switch org option even if I belong to more than one organization.
I also want to undertsand, what is relation between the org created in Grafana, and the main organization unit in LDAP?
For example: our LDAP server has OU= ABGM.
I created myOrg and yourOrg in grafana, then what do I need to configre in ldap.toml?
Is there any step by step guide with examples?
