Kentico 10 - How do I update the username of an existing user? - kentico

Question

Using a kentico 10 website with claims based authentication. We have the facility to update their email address in the external system. So what I want to do is update the user's email address and username by looking up based on the external userid from our sso platform.
var existingUser = UserInfoProvider.GetUsers().Where("ExternalGuid", QueryOperator.Equals, userId).FirstOrDefault();
if (existingUser.IsInSite(SiteContext.CurrentSiteName))
UserInfoProvider.RemoveUserFromSite(existingUser.UserName, SiteContext.CurrentSiteName);
loggingInUser = UserInfoProvider.GetUserInfo(existingUser.UserID);
loggingInUser.UserName = e.UserName;
UserInfoProvider.SetUserInfo(loggingInUser);
I'm getting the error:
The user with code name 'ac.aa#test.com' already exists.
This is happening on that SetUserInfo line. So I'm thinking there must be another way to update the username properly.

Answer 1

You need to do a few things:
Check if the user exists already:
UserInfo ui = UserInfoProvider.GetUserInfo(newUserName);
if (ui != null)
{
// user exists with new username so don't continue
}
Check if the username can be used as a username (no spaces, special characters, etc):
if (!ValidationHelper.IsUserName(newUserName))
{
// username cannot be used as a username
}
Check if the username is reserved or not:
if (UserInfoProvider.NameIsReserved(siteName, newUserName))
{
// reserved username so cannot use it
}
I'm willing to bet the username is reserved or not valid which is why it is not saving. The assignment you have done should work without issue.
It also looks like you're performing this update in a global handler so this could cause problems with a few things. So you may have to perform that username update later on or simply write a record to a custom table and then update it from there based on the event of creating those records in the custom table.
So I'd debug through your code and verify it is working properly by removing it from the global event handler, if it works, then it's an issue with having too many things happen at one time.

Try using SetValue(string columnName, value) method, I just tested this one and it worked fine:
UserInfo updateUser = UserInfoProvider.GetUserInfo("NewUser");
if (updateUser != null)
{
// Updates the user's properties
updateUser.SetValue("UserName", "NewUserName");
// Saves the changes to the database
UserInfoProvider.SetUserInfo(updateUser);
}
For some properties/columns, which are acting like "read only", you need to use the SetValue method like it was a custom field (API examples)
