Errors in Active Directory Operations in ESXi 4.1

Asked By 0 points N/A Posted on -

AD-Share Integration – Errors in Active Directory Operations in ESXi 4.1. We upgraded from ESXi 4.0 to 4.1, to use the Active Directory Authentication for users. Now we get a mysterious error when trying to join a domain with an user:  

  • "Errors in active directory operations".

We can reach the AD Server running (Win2k3) from the ESXi host and that Active Directory is performing well with other servers. The Export of the ESXi Logs gave no clue what happens.

Errors in Active Directory Operations in ESXi 4.1


Dear Laura zahn,

According to the error message "Errors in Active Directory operations", I think this error might occur when the network firewall is blocking some required ports. To resolve this issue, ensure that the following required ports for both UDP and TCP are open for communication between ESX/ESXi and Active Directory: 
  • Port 123 NTP
  • Port 88 Kerberos
  • Port 389 LDAP
  • Port 135 RPC
  • Port 139 NetBIOS Name Service
  • Port 137 NetBIOS Session Service SMB
  • Port 445 Microsoft-DS Active Directory, Windows shares (SMB over TCP)
  • Port 464 Kerberos change password changes
  • Port 3268 Global catalog search
Hope this may help you.
Best of luck.
