SCC - New User creation under new Security configuration [Login failed]

Hi,

I want to create a new user giving it a few rights (maybe roles other than administrator) in SCC. Also, I want to create the user as a part of a new security configuration.

So, I have created a new login by the name of "supdev1" from Application>Administration>Security>Logins.

Now, I went ahead and created a new Security configuration with the name "developer" and using the PreConfiguredUserLoginModule added supdev1 to it. Also, I assigned the "developer" configuration to the default domain (I'm not using any other domain at the moment).

I modified the properties of the configuration and provided a password to supdev1. All these additions & modifications were done from the default supAdmin administrator account. The problem is, when I log out and try to login using the supdev1 account, it says 'Login failed'.

Is there anything I'm missing out on? When I try to create supdev1 under the default admin Security configuration, it works fine. But it doesn't work when it is under a newly created Security configuration. What am I doing wrong?

Any help would be appreciated. I thank you all for your kindness, in advance! 😊
