When I try to edit do crontab for a user with a long username on solaris 10 I get this error:
crontab: login name too long
Is this a known problem and is there a solution for it (without changing the username)?
The username is 27 characters long.
I never saw that before.
But, while we don't discover how to fix this issue, try to edit the crontab file by vi command.
It will help you meanwhile.
After some quick googling it appears that many of Sun's unix tools follow the Unix convention of 8 or less character usernames. It seems that Solaris will allow you to use longer usernames, but it is not a certified or supported configuration.
