Table Of Contents
n Access control lists (ACLs)
View LDAP contains directory entries that represent Horizon 7 objects.
n Remote desktop entries that represent each accessible desktop. Each entry contains
references to the Foreign Security Principal (FSP) entries of Windows users and groups in
Active Directory who are authorized to use the desktop.
n Remote desktop pool entries that represent multiple desktops managed together
n Virtual machine entries that represent the vCenter Server virtual machine for each remote
desktop
n Horizon 7 component entries that store configuration settings
View LDAP also contains a set of Horizon 7 plug-in DLLs that provide automation and notification
services for other Horizon 7 components.
Note Security server instances do not contain a View LDAP directory.
LDAP Replication
When you install a replicated instance of Connection Server, Horizon 7 copies the View
LDAP configuration data from the existing Connection Server instance. Identical View LDAP
configuration data is maintained on all Connection Server instances in the replicated group. When
a change is made on one instance, the updated information is copied to the other instances.
If a replicated instance fails, the other instances in the group continue to operate. When the failed
instance resumes activity, its configuration is updated with the changes that took place during the
outage. With Horizon 7 and later releases, a replication status check is performed every 15 minutes
to determine whether each instance can communicate with the other servers in the replicated
group and whether each instance can fetch LDAP updates from the other servers in the group.
You can use the dashboard in Horizon Administrator to check the replication status. If any
Connection Server instances have a red icon in the dashboard, click the icon to see the replication
status. Replication might be impaired for any of the following reasons:
n A firewall might be blocking communication
n The VMware VDMDS service might be stopped on a Connection Server instance
n The VMware VDMDS DSA options might be blocking the replications
n A network problem has occurred
By default, the replication check occurs every 15 minutes. You can use ADSI Edit on a
Connection Server instance to change the interval. To set the number of minutes, connect to
DC=vdi,DC=vmware,DC=int and edit the pae-ReplicationStatusDataExpiryInMins attribute on
the CN=Common,OU=Global,OU=Properties object.
The pae-ReplicationStatusDataExpiryInMins attribute value should be between 10 minutes and
1440 minutes (one day). If the attribute value is less than 10 minutes, Horizon 7 treats it as 10
minutes. If the attribute value is greater than 1440, Horizon 7 treats it as 1440 minutes.
