You can add an Active Directory provider to an access zone as an authentication method for clients connecting through the access zone. Implementing this evening. The authentication process takes place through providers such as Active Directory (AD) or MIT KDC. Your clients should have the proper search domains/suffixes configured. So they could not authenticate. See if the failure happens consistently on any specific nodes.. Additionally, your question about the DNS setup of smartconnect zone, it is important for load-balancing to work correct, and if you are using round-robin, you can test by simply running nslookup on the node name repeated, and you should constantly rotate the ip address (if other clients are using it, and you dont have many nodes, it could come back to the same one), Having a wrong DNS record usually causes all connections to use the same node (generally node 1 or the lowest node number). Subnet0, Subnet1, and Subnet2. Really glad to hear you have it resolved! You can add an Active Directory provider to an access zone as an authentication method for clients connecting through the access zone. Under Access Management, click on Active Directory. 0. Each Active Directory provider must be associated with a groupnet. This process is … 1) File Sharing > Authentication Sources > Active Directory. Isilon Directory and Share Configuration .

Subnet1 is what a few legacy servers use to connect to Isilon, and it is in a firewalled VLAN. as far as logs go, you have way too many. OneFS will build that token based on which authentication providers are configured. You can join the EMC Isilon cluster to an Active Directory (AD) domain by specifying the fully-qualified domain name, which can be resolved to an IPv4 or an IPv6 address, and a user name with join permission. Above someone suggested turning on AD notifications, that is a bad idea, long story short, it was on by default in the past, and would cause all kinds of false notifications.. you should be monitoring AD from your monitoring software, not form the NAS. Would it be possible that this current DNS setup is causing this random prompt if each system has several different mapped drives to different shares on the Isilon?

We use Isilon to create home directories of hundreds of users as it is very … And it appears to be working for the users. You can actually run nslookup, set the server to the service ip, and then lookup the name of your smartconnect zone, you should get back an IP address according to your load-balancing method.. methods other than round-robin are slow to change the node that is being distributed, but round-robin should always cycle through the ip's available as each new reuqest happens. (Windows Vista or newer, or Server 2008 or newer). In my opinion this far, the Isilon platform is the ideal solution to deal with a mixed protocol environment due to it’s integration with authentication services such as Windows Active Directory or any LDAP service.
