In Usernames on top, lifting username length restrictions, there is a lengthy discussion about lifting the max username length restriction.
The first post gives an example of the length being increased to 40, but Usernames on top, lifting username length restrictions (post 25) says that it has been officially bumped from 15 to 20.
Is it safe to make it more than 20 characters? The reason I ask is because we’ve tied our Discourse implementation to our LDAP system for SSO, and we’re using the LDAP usernames as the Discourse usernames … and some of our users have got very long names, e.g. moorthy.baskaravenkatraman-sambamoorthy.
What is the maximum length that the system has been tested with? I don’t want to break Discourse by putting in a value that is too high …
