Username length

I have been told that my college wants to implement LDAP. This creates a problem for me because my users active directory names and email user names differ from their unix system logins. Is there any way to make the Unix usernames more compliant to my user's other account usernames??? We use lastname first initial for the email accounts... This creates a problem due to the eight character constrants of Solaris. Is there a way to make the unix system accept more than an eight character username??? Any insight is appreciated.......

It matters what version of Solaris, but it will 'take' more than eight characters for a username. When you login, it will only really look at the first eight (so you may have a problem with some names...and then you will also have an issue with password resets - you have to do passwd humperdinks for the account for Sam Humperdink ( humperdinks ). If they just try to do passwd, it will come back and state no such user.
