Ldap error trying to authenticate

While trying to authenticate grafana console using ldap getting error trying to authenticate.
But the ldap user which tried to login is created in grafana users with new organisation name same as ldap user login name.
The ldap user tried to authenticate before can login after deleting the newly created organization and assigning the organisation (already assigned org id in ldap config file) to the user from grafana console.
For every ldap user inside the mapped group shows this trying to authenticate error and a new organisation is created in the name of authenticating username.

is there any solution or anyone had this issue before?

The error got resolved by allow_org_create to TRUE in grafana config file.
