Will changing the join user account affect already joined Safeguard Authentication Services clients? (4373357)

Will changing the join user account affect already joined Safeguard Authentication Services clients?

Will changing the join user account affect already joined Safeguard Authentication Services clients?

For example changing the join account name or password.

 

The join user account is only used for the initial computer object creation during the join. 
This user (or their password) is not used from that point onwards.
Therefore changing the user name or the password will not affect clients that are already joined to the domain.

For any future Active Directory communication, the host/ computer object is used along with the host.keytab file which contains the password hash of the computer object.
