"I found that in Chrome 94 Google has deprecated some private network access from public sites, so if the site is requesting a script and it gets directed to a private network or localhost, it will throw this error. Migrate from secure perimeter to Zero Trust network architecture. In the example above, where the DFS mount point was \company.co.uk\dfs, and the referrals were to servers \UK1234CSC123\dfs and \UK1923C4C780\dfs it would be necessary to have a domain search of company.co.uk in order for these to be completed to \UK1234CSC123.company.co.uk\dfs and \UK1923C4C780.company.co.uk\dfs. Provide access for all users whether on-premises or remote, employees or contractors.

Currently, we have a wildcard setup for our domain and specific ports allowed. Client then connects to DC10 and receives GPO, Kerberos, etc from there. Application Segments containing the domain controllers, with permitted ports Ah, Im sorry, my bad assumption! Understanding Zero Trust Exchange Network Infrastructure will focus on the components of Zscaler Private Access (ZPA) and the way those components shape the . And MS suggested to follow with mapping AD site to ZPA IP connectors. Protect all resources whether on-premises, cloud-hosted, or third-party. Ensure connectivity from App Connectors to all applications ideally no ACL/Firewall should be applied. From an Active Directory perspective you may create an application segment for each regions or countries AD Servers a company may have 1000 Domain Controllers across 100 countries, and a single Application Segment with 1000 entries may not be manageable. In the AD Site mode, the client uses the Active Directory Site data returned in the AD Enumeration (CLDAP) process and returns this data to the SCCM Management Point. VPN gateways concentrate all user traffic. Security Service Edge (SSE) | Zscaler Internet Access Continuously validate access policies based on user, device, content, and application risk posture with a powerful native policy engine. Discover the powerful analytics tools that are available to assess your cyber risk and identify policy changes that will improve your security posture. o Application Segment contains AD Server Group This is then automatically propagated toActive Directory DNS to enable the AD Site Enumeration. Zscaler secure hybrid access reduces attack surface for consumer-facing applications when combined with Azure AD B2C. Other security features include policies based on device posture and activity logs indexed to both users and devices. Zscalers centralized data center network creates single-hop routes from one side of the world to another. This relies on DNS Search Suffixes to complete the shortname to an FQDN this also has an effect on how Kerberos Tickets are generated so it is imperative that DNS Search Suffixes are created properly. zscaler application access is blocked by private access policy. We only want to allow communication for Active Directory services. Copyright 1996-2023. Give your hybrid workforce optimal protection with unified clientless and client-based remote access. A cloud native service, ZPA can be deployed in hours to replace legacy VPNs and remote access tools with a holistic zero trust platform, including: Connect users directly to private apps, services, and OT systems with user identity-based authentication and access policies. Apply App Connector performance and troubleshooting improvements, Ensure Domain Search Suffixes cover all internal application/authentication domains, Ensure Domain Search Suffix has Domain Validation in Zscaler App ticked, Create a wildcard application segment for Active Directory SRV lookups, including all trusted authentication domains, Deploy App Connectors within Active Directory Sites IP Subnets, Associate Application Segments with Server Groups containing appropriate App Connectors, App Segment for WDC - Contains dc1, dc2, dc3 - WDC ServerGroup, App Segment for Arkansas - Contains dc4, dc5, dc6 - Arkansas ServerGroup, App Segment for Cali - Contains dc7, dc8, dc9 - Cali ServerGroup, App Segment for Florida - contains dc10, dc11, dc12 - Florida Servergroup, App Segment for Wildcard - i.e. Read on for recommended actions. Companies deploying Zscaler Private Access should consider the connectivity workstations need to Active Directory to retrieve authentication tokens, connect to file shares, and to receive GPO updates. o Ensure Domain Validation in Zscaler App is ticked for all domains. Return Group Policy Object ID, Client connects to Domain Controller using SMB2 (TCP/445) and retrieves Machine Group Policy Objects, Client requests Kerberos user TGT and Service Ticket from AD Domain Controller for CIFS, Client connects to Domain Controller using SMB2 (TCP/445) and retrieves User Group Policy Objects, Received Kerberos tickets for machine and user, and Service Tickets for LDAP and CIFS, Retrieved Group Policy Object descriptors via CLDAP, LDAP, DCE/RPC, and CIFS, The mount point \share.company.com\dfs is a global namespace, User would receive a Kerberos Service Ticket for CIFS/share.company.com, User would retrieve mount points \server1\dfs and \server2\dfs which would need to be completed to FQDNs \server1.company.com\dfs and \server2.company.com\dfs, Upon making the decision which mount point to connect to, the user would receive a Kerberos Service Ticket for CIFS/server1.company.com or CIFS/server2.company.com. Its entirely reasonable to assume that there are multiple trusted domains for an organization, and that these domains are not internet resolvable for example domain.intra or emea.company. Application being blocked - ZScaler WatchGuard Community *.domain.local - Unsure which servergroup, but largely irrelevant at some point. Users connect directly to appsnot the networkminimizing the attack surface and eliminating lateral movement. Configure custom policies in Azure AD B2C if you havent configured custom policies. Watch this video to learn about the various types of reports available in the dashboards of the Admin Portal. I did see your two possible answers but it was not clear if you had validated that they solve the problem or if you came up with additional solutions not in the thread. Active Directory In this way a remote machine which is admitted into Client to Client can accept inbound connections based on policy. A machine with ZPA on does not register within the internal DNS and is not resolvable and the app connectors are in theory inbound only from ZPA OnPrem? A roaming user is connected to the Paris Zscaler Service Edge. Instantly identify private apps across your enterprise to shut down rogue apps, unauthorized access, and lateral movement with granular segmentation policy. As the worlds most deployed ZTNA platform, Zscaler Private Access applies the principles of least privilege to give users secure, direct connectivity to private applications while eliminating unauthorized access and lateral movement. This value will be entered in the Secret Token field in the Provisioning tab of your Zscaler Private Access (ZPA) application in the Azure portal. o UDP/389: LDAP Reduce the risk of threats with full content inspection. o *.emea.company for DNS SRV to function For more information, see Configuring an IdP for single sign-on. e. Server Group for CIFS, SMB2 may contain ALL App Connectors, however it could be constrained geographically as necessary. The issue I posted about is with using the client connector. Here is a short piece of traffic log - i am wondering what i have to configure to allow this application to work?
