Vcenter Server Appliance lose sometimes connect to Active Directory

[ISAGmbH]

Hello,

we have the vCenter Server Appliance 5.0.0.3324 Build 472350 for 3 Hosts.

Service Version: 5.0.0-455964

Sometime we can not connect to the vCenter with the users from Active Directory.

For fast repair i connect  me with  the Managmend Console from the Appliance with the Browser  and under Authentication and Active Directory

i insert the Administrator user with password again. The Checkbox Active directory Enabled is Enabled

Then i restart the ESXi Services again.

With this thinks i can now add  under the permissions in vCenter my Users from Active Directory now.

Why is this,  who can help me to fix this problem, sometimes is this 2 times in the week.

Disk space is OK

For vCenter i have the embedded Database

Thanks,

TWSS

Hi,

I had a problem similar of yours, but in our enviroment our AD had 2 interfaces with 2 different vlans, one for managment, and one for service.

and when we ping from vcenter to our AD, sometimes we had reply from managment ip address and sometimes from service ip address.

So, if your case is similar of mine, the first think that you shoud do is to login in the vcenter appliance and ping to the AD, after that you can add a reference to ad in the /etc/hosts in the vcenter appliance.

It is possible to add the vcenter to active directoy by command line, using this command domainjoin-cli join (domain) user (with permissions to join domain).

you can try this too.

thanks
