Under Netbox Administration, add a permission to this group (ex: dcim.view_site):

Try to logging as user 'netbox'
Logging established and only view Site is possible
Logging is OK, View Site is not allowed

I have an old group (before the last upgrade (v2.8.0) and it's works.
To complete, if I manually attach the new user to the group in Netbox Administration, it's works :

and

With my old group, it's not necessary to manually attach user to the group.

I am seeing the exact same issue.
Same issue on 2.9.4.
Anyone know of a fix ?
Running into a similar issue in 2.9.9 as well
I'm running v2.9.10 and have been tinkering with this as I was initially seeing some confusing behavior.
For the most part, everything seems to be working fine with the LDAP group permissions mapping - with the exception of scripts and reports. I can't seem to get a user with View/Add/Change/Delete rights on "scripts" and "reports to be able to access or run either. Both options are greyed out in the menu.
[edit] I'm continuing to look in to this, just putting this info here as notes on my findings/observations


Edit 2:
The running reports & scripts issue was supposedly due to new "run" permissions being required, however adding "run" as described in the docs doesn't seem to be doing it.
