[AccessD] Restrict # of User Logins to Access Part 2

But isn't there a delay in clearing out locks in the ldb file?  If they
shut down on one machine and went to another, is there any guarantee
that the lock would be gone?

My solution to use the .ldb should work fine with the BE .mdb.

Well, in the midst of explaining myself more clearly (seems I have to do
that a lot at my age...), I discovered I may have left out a VERY vital
detail.  Each user's application resides on his or her local machine, so
the only way to see who's logged in will have to be through the secured
mdw file.  In other words, I won't be able to have a common table in the
Front End to use for comparisons or times.  Everything will have to
reside in the BE, where there are no queries or forms, just tables.

This may or may not make any difference, but I thought you all should
know that.

Charles:

Well, phooey.  Once again I made myself NOT clear...like mud.  Sorry.

What I meant was the same username (Phred, for example...), can't be
logged into the db more than once, at the same time.  Regardless of what
terminal or workstation they are on.  If Phred is in the DB once,
another user (or the same one at a different computer) can't login with
Phred again.

And, now that you mentioned that, she also did say she wanted to
restrict their times in the database.  The database is online within
their offices 24/7, except during backups, but she wants to restrict
them to using it from, say, for example, Monday through Friday,
0900-1500, only.  I haven't thought about that too much yet, but it
might not be too hard to implement.

Greg,

Once in a lifetime?  Or once in a day?  Or once in an hour?

If it is the first, then you have a separate table with flags you set
for each user.  Once the flag is set, they are locked out forever.  For
the latter options, you add a date/time field to record when they
accessed and then compare the time of their next attempt to access to
see if the proper length of time has expired.

Hello everyone!

I got a request from a client that I'm not sure how to handle...and I
hedged enough so as NOT to commit to anything until I have it figured
out.

Their current system is in Access 97, using full Access's security. It's
setup fairly well, with users being members of groups and rights
assigned to the groups.  Now she's thrown me a curve.  She wants to
allow users from another department to login to her system, but ONLY
ONCE (her reasoning is sound - she does not want users from another
group tying up all her resouces and licenses with multiple logins). That
is, that username can only login to the Application once...one
concurrent usage.

Windows security would do this easily, but Access 97's doesn't have a
place to select the number of logins per user.

Any suggestions on how to do this?  I've just had a second temporary
crown put in this morning (since last week), it's fairly early, I've NOT
had sufficient coffee, and I'm a bit fuzzy (fuzzier??) around the edges
this morning and it's not readily apparent to me on how to do this.

Thanks!!
