RE: IFS mapped drive issues -- MIDRANGE-L

Paul,
Been years since I did anything with QDLS.

Not sure if there could be a "system distribution directory" entry issue
with the "3'rd simply kept trying to connect" issue ?

We try to avoid any/all "system distribution directory" - don't think we have any remnants.

IBM comparison of QDLS and other File Systems (note limitations, comparative speed, max links):

Another link regarding QDLS and IFS:

A link with a question about QDLS access (maybe you have seen):

Gary,

Good link for reference. Does explain what happens when a user changes their password.
IPL'd over the weekend for PTF apply.
Same IFS mapped drive issue for same user.
I remote assistance in to watch and actually see the issue.
2 mapped drives to qdls working.
3'rd simply kept trying to connect, however, never actually errorred out.
Had the user delete the 2 QDLS, create one new one to QDLS I'm wondering if there is a QDLS limit for mapped drives.

Paul,
This link to an IT Jungle article may help explain "caching the password", and it has a link to an IBM site.

Had issue today again, user had to change their AS/400 password, mapped drives failed, user was disabled, fixed using go nets.
I think this all boils down to authentication issues.
It appears the IFS mapped drives may be caching the password, when password changes, the mapped drive is trying to authenticate with the old password, account is then disabled with netserver.
Sometimes, it is as simple as reenabling the usrprofile.
Other times, resolutions are varied.

Yes, third party packages make it harder to implement things like program only access in which the only way to access data is by programs which adopt authority. Thus handling the security of multiple databases. When we had the BBU's the people handling customer X's data could not see customer Y's data. We had plants dedicated to particular large customers.
Or, even of more concern, they buy from each other. You sure didn't want
01 being able to see the cost of an item produced by 02 and sold to 01 at the profit margin.
I feel your pain.

I wish that was an option.
Each DB is for a different subsidiary, security, tax, audit other factors.
Also, they are all 3rd party packages, need to abide by those requirements.

If the databases are owned by different group profiles, and you're concerned about new objects each user may create getting the right group profile assigned, this can be an issue.
We ended up consolidating databases. The business was ripe for it.
Instead of Dilbert's BBU's (battling business units) they were all consolidated into one happy company.

Is this because one PC may be shared between several users?
Or, is this because one PC user may have mutiple IBM i signon's? For example SUSAN may have SUSAN01 for database 01 and SUSAN02 for database 02. We used to have this crud.

One Windows user may have 3,4,5,6 iSeries accounts, they cannot match. We

run many different apps, each requiring separate accounts for login.
If we had only one iSeries app, I agree, they could then match.
I setup and tested Enterprise Identity Mapping (EIM) along with Kerberos, again, if we only had one app, this could work.

I am going to revisit Net Use, see if I can it to work for IFS

None of our Windows accounts equal our iSeries accounts.

I disagree with this philosophy. Both Windows, and IBM i, should have their security taken seriously. Critical data is stored on both. Done right, then it's no great risk to have them be the same. Done REALLY right and it could actually be MORE secure to have them the same. Like SSO with biometrics.
