Open Source Document Management System | OpenKM

Hi all,
i have OpenKM Version: 6.3.0 (build: 8156).
when i create e new user named "EJV-BKJV-VP", the system give me e error message "ID Invalid identifier", and i can not create this user.
the user "EJV-BKJV-VP" does not exist in the users database!
somebody has an idea?

Add PrintScreen

That is caused because in default configuration the character "-" is not allowed, simply go to administration -> configuration parameters and looking for parameter named principal.identifier.validation that has a value ^[a-zA-Z0-9_]+$ edit and add the character "-".

I think character "-" is special character and can not be included directly and should be escaped, try with it, I'm not totally sure ^[a-zA-Z0-9_\\-]+$ , see I've added at end \\-

Thanks for the solution. It's work.
