We currently have a user set up with an incorrect username. What is the easiest

You could deactivate that user and create a new user with the desired name.

As long as the username is not the same set of characters but different case. For example, if my user is Eduardo.fuentes I can't deactivate it and create eduardo.fuentes because since 7.4 Eduardo.fuentes = eduardo.fuentes only for the validation of available usernames.

In that case you will have to use the Rename Users plug-in to rename Eduardo.fuentes to eduardo.fuentes_tmp then eduardo.fuentes_tmp to eduardo.fuentes.

thank you eduardo.fuentes...

why Eduardo.fuentes = eduardo.fuentes is not apply in Login Page ....

many of users type a first character in capital case as long as all email service authentication(Gmail ,hotmail) that apply Eduardo.fuentes = eduardo.fuentes

That's a design consideration in the product also described in the documentation: forum.appian.com/.../User_Management.html

Hi Eduardo, even we were facing the same problem and reacted the problem in the same way by renaming it to a temp value and then renaming back to required value. Rename worked but the problem is that we are getting this error in logs for that user "ERROR org.hibernate.util.JDBCExceptionReporter - Violation of UNIQUE KEY constraint 'usr_username_uc'. Cannot insert duplicate key in object 'dbo.usr'. " Also since the user's entry in usr table is with old username, the user cannot post news feed. Is updating the usr table a good option? Can the plugin be updated to handle this?

Forgot to mention that part. Yes, you'll have to rename it in the usr table too.

Thanks Eduardo. I just want to make sure that updating the usr table in primary DB won't have any bad outcomes(The overall idea of changing something in Primary DB).

This is the only scenario where you have to update the Primary DS and has to be done only when you can't really create a new account for a user instead and you really need to rename the user.

Until there's an automated way to rename users from the UI this is required.
