hello Adam,

thank you for the information. I've seen that migrating from 1.53 (actual)
to 2.0 will further complicate things so I think that I will abandon these
enhancements of the security database. What I wanted to accomplish with
these changes was to enrich the security database with some advanced
characteristics like:

- a flag indicating if the account is enabled/disabled
- a flag indicating if password never expires
- a flag indicating that the user is allowed to change his/her password
- a flag indicating that the user must change the password at the first
connection
- a field indicating the password duration in days
- a field indicating the date of the last password change

More or less like the Windows accounts. But I feel that it will be
impossible unless these enhancements are implemented directly into Firebird.

Regards
Salvatore
