I have a server that uses specific login/passwords. And through random
testing i noticed that the passwords are not case sensitive. Can this be
changed so that the passwords ARE case sensitive?
thanks,
BenHi,
For a Case insensitive sort order/carecter set it is not possible. If you
have a Case sensitive sortorder/char set then automatically
passwords will be case sensitive.
Thanks

actual password supplied by the user, and the other is the password
converted by to all uppercase letters. This enables case-insensitive
validation of passwords (for case insensitive collations). Although this
behavior is convenient for many users, it makes password-guessing attacks
easier by reducing the number of possible passwords
In SQL 2005 only the actual password is stored. A password entered by a user
must match the password stored in the server (regardless of collation,
however the username can still be in a different case). If a password does
not match the password stored in SQL Server, the login fails. If the precise
case of the password characters is forgotten, the password must be reset.

Actually it because of *Collation setting* look for your collation and
change it accordingly to case sensitive from case insensitive .

Password's case sensitivity
Hi,
somehow my Sql Server's passwors are not case sensitive. I thought sql
server's login passwords are case sensitive.
Am I worng?
How do I change my SQL Server back to the case sensitive passwords?
Please help..
Thank you
SamHi
Passwords case sensitivity is based on the collation of the installation. If
you install with a non-case sensitive collation, the password will not be
cases sensitive.

which are upgraded from 7.0 to 2K and so the defautl collation of 7.0 was a
case sensitive. (Not usre right now).
But if I want to keep all my client data and other code to be case
-insensitive but all my login passwords to be case sensitive , can I do that
?
How can I do that?
Please let me know..
Thank you again..

I want to keep the collation of all the DBs on the server same as what I
have at present (case in-sensitive) but only all my login passwords should b

case sensitive.
Can I do that?
How?

However, as I mentioned in my previous response, mixed collations will have

thoroughly test your applications before implementing this in production.

Bu insterad of rebuilding my master database, Can I change the collation of
the password column of the sysxlogin table?
This is just a guess. I think you must have thought of this but I still want
to ask you this question.

Changing system table schema is not supported so you would this is at your
own risk. The supported method is a mixed collation environment with a
case-sensitive instance default collation and case-insensitive collation for
user databases. Of course, mixed collation caveats apply.
Hope this helps.

Password: case sensitive
I installed SQL 2000 with default sort order. I though the password for SQL
logins is case-sensitive but it is not. Is that correct?
Thanks.Yes ...the passwords are not case sensitive... because of the collation
level . I beleive you might be able to change the collation for the password
column in sysxlogins table. Not tried it out but might be interesting if it
can be done
