Having upgraded our Panorama from 4.1.7 to 4.1.8 - we can no longer use the LDAP user authentication.
The user constantly gets "invalid username or password" (same message on the Panorama) - yet this worked without any problems with 4.1.7
On Panorama - one can see that in the LDAP profile - the Base option is never getting populated (dropdown option is only "none" rather than domain name).
Is this a new "feature" ?
We are having the same/similar issue on a PA-2050 and on Panorama.
The reason why I write similar is because I noticed the problem after not being able to log into the PA at all after upgrading after some time.
When I looked at the cpu usage on the PA (show system resources follow) it showed that the authd is using 100% cpu and this "blocks" all other attempts to authenticate on the PA (localusers, radius, ldap etc..).
I still had problems after downgrading to version 4.1.7, but then I noticed a error message in the systemlog regarding ldap not being able to connect to the ldap server on SSL..
I disabled SSL and changed the ldap port to 389 and everything seems to be working OK.
I have opened up a case on support (#00096705) and the issue has been escalated to TAC.
This is specifically LDAP authentication into the administrative website of the Palo Alto *only*, correct?
I am having other issues in 4.1.7 that I really need resolved and are known fixes in 4.1.8. I use LDAP for user based rules, however my admin users are all locally defined to the PAs.
