Re: What is the impact of changing the 'qcadmin' user password?
Regardless of the connection type, the user has to be authenticated. That means the user's password has to be submitted during the process of connecting.
If the connection type is "UI" then the connection was made through the ALM/QC UI, either the Explorer application or through the general web application in a browser.
If the connection type says OTAClient, then somebody has created and is running a program that is using the Open Test Architecture API to establish a connection to the ALM/QC system. The UIs generally don't use this type of connection unless somebody has done something interesting through customizing workflow code.
So, you need to look at the Host information for the OTAClient application. That will tell you what system is running the code. Then go to that system and try to find out what application is running that might be using the API to connect to the ALM/QC system. It could be a compiled program, or an interpretted language program. In either case, that code will need to be updated to submit whatever new password you've entered for the "qcadmin" user.
