Where to find info about DEFAULT value

[rabbtux rabbtux]

All,

I see reference to setting DEFAULT in mysql database tables.

I need to set the default value of Acct-Interim-Interval = 60s for all
users.  Can I just put this in my radreply table:
user     attribute  op   value
-----------------------------------
DEFAULT, Acct-Interim-Interval, :=, 60

Will this make sure that any user that doesn't have this attribute set
elswhere, will get 60?

Thanks
