Failed to authenticate using ldap when migrating to 9.5.1

Just upgraded from grafana 9.4.3 to 9.5.1, the ldap autentication process which was working find in 9.4.3 stop working.

Don’t know if it is related, message in grafana.log indicate:

logger=context userId=0 orgId=0 uname= t=2023-05-04T12:54:58.555351914+02:00 level=error msg=“Error while trying to authenticate user” error=“cannot remove last grafana admin” remote_addr=w.x.y.z traceID=

LDAP is having a single user, which has been granted admin privilege in grafana using org_role.

Seem this was due to not having any user with “grafana admin” privileges.
