Openfire 3.6.4 - username length limitation


I’m using openfire 3.6.4 with a postgresql database.

I’m currently having an issue with the length of the “username”. It’s limited to 64 character. It’s sadly not enough for my system… and I want to extend the limitation to 255 characters. I have altered my database in order to handle 255 character long username but I have not looked at the code for the moment.

Do you think that this “upgrade” could cause problem with the code?

Thank you,
