I'm evaluating Loadmaster for my customer. I have deployed Loadmaster from Azure marketplace, and I am trying to authenticate users to IIS server from AD (not Azure AD, but on-prem, DC is in Azure IaaS).
If I disable authentication from ESP options, I can access the website. However, When I try to preauthenticate users, it fails. I have monitored traffic to DC (LDAP endpoint) and it succeeds, Loadmaster gets answers.
ESP User log shows:
Mar 14 20:06:46 ******** l7log: 10.1.0.41:443: User ****** denied access from x.x.x.x
SSOMGR Audit Log shows:
Mar 14 20:07:03 ******** ssomgr: #40401# group_processing: Blocked access - user not in approved group SID(s) for VS 
I have tried both Group name and group sids, no difference. I've been banging my head into wall for an entire day - any help is greatly appreciated.
