How To Reset an NSX-T API Local Account Password and Make the Account Active

In this post, let us see how to reset a password and make the account active in NSX-T.

Remember that this account was created using API as you can’t create local accounts using NSX-T UI. My NSX-T version is 3.2.2.x.x

Back Story: one of the local accounts which I created for skyline collector in our NSX-T environment password was expired. Hence, I had to use the API to Update the User account password and status to make the account ACTIVE again.

Use an API Editor like Postman to get the required data as shown in the screenshot below:

In the GET field, you will be providing the following code.

https://<nsx-t hostname/IP-address>/api/v1/node/users/<user-id>

You can get the user-id pretty easily by going to System and User Management in NSX-T UI and get the user-id. In the above example my user-id is 10003. Then go to the Authorization tab and provide the username and password of the NSX-T Manager where you want to make these changes. Then click on Send option to get the required info.

you will get the data as the below screenshot.

You will observe that the last password has been changed 95 days ago, password change frequency is every 90 days, status is password expired and the actual username (in this case its labprdsky_nsxt)

you will have to change the body of this into the below values

{
"full_name": "Guest User1",
"last_password_change": 1,
"password_change_frequency": 999,
"old_password": "<old_password>",
"password": "<new_password>",
"password_reset_required": false,
"status": "ACTIVE",
"userid": 10003,
"username": "labprdsky_nsxt"
}

You can change the password_change_frequency from 0 to 9999, you will have to provide the old password which is expired and the new password for this account and change the status to ACTIVE.

We will copy the above code into the body of the next PUT statement as shown below

Change the GET to PUT and insert the above code with the changed values in the body as the screenshot shown above and click on Send

The output will be displayed as below

{
"full_name": "Guest User1",
"last_password_change": 0,
"password_change_frequency": 999,
"password_reset_required": false,
"status": "ACTIVE",
"userid": 10003,
"username": "labprdsky_nsxt"
}

The above output is in code form in case you want to copy it.

Now you can do the above GET command to get the status of the user and you will see that this account shows as active and the password change frequency is now 999 days.

Final output for GET for that user 10003

Hope this writeup helped you to unlock and reset the password of an local user created using API in NSX-T.

How to Change the admin@local account password in VCF 4.5.x (UNOFFICIAL)

You might have come across an issue where the VCF REST API User account admin@local password is either lost or need to reset the password of this account.

NOTE: This is NOT an official way to do it according to VMware and is meant to be done under the supervision of VMware Support.

Login into the SDDC Manager as vcf and go to the root user prompt

sddcmanager#

type the following commands to reset the password of admin@local account on the sddc manager

mkdir -p /etc/security/local
chown root:vcf_services /etc/security/local
chmod 650 /etc/security/local
echo -n "" > /etc/security/local/.localuserpasswd
chown root:vcf_services /etc/security/local/.localuserpasswd
chmod 660 /etc/security/local/.localuserpasswd

type the following command to set a new password -  in this example it is NewP@SSW0rd010

echo -n 'NewP@SSW0rd010' | openssl dgst -sha512 -binary | openssl enc -base64 | tr -d '\n' > /etc/security/local/.localuserpasswd

Once you have changed the password, I would recommend to restart the sddc manager services using the following command

/opt/vmware/vcf/operationsmanager/scripts/cli/sddcmanager_restart_services.sh

Once the services are restarted, you can verify if the password for admin@local has been successfully changed by going to lookup_passwords

in lookup_passwords, use the admin@local to check if it can pull the passwords from the SDDC Password Manger.
