2 Users with the same name/shortname on the same machine

Hello,
What will happen if:
There is a local user called Bob and a network user on a server called Bob? Before you even post anything, please let me know if you have actually SEEN this before. I know something will happen, I just don't know what. Again, 2 different users with the same name. YES it is possible to create, but I have not tested it yet. One home is on the local machine and the other is a network home directory. I didn't post this in the server section for this reason...the question is about a client machine running 10.5.4 not server, so it belongs here! Thanks to all who help and my guess is a dialog box pops up with a choice of network or local? Not sure, but it is going to be quite an interesting topic.

Thank you both. It seems I need to test this because it doesn't seem anyone has ever run into this situation. The first thing I need to ask is will it do any damage to the system files if a user logs in with the same resolving name?I know I know the UIDs are different, but maybe have the same shortname? Not sure if it will work. The network users authenticate via LDAP and the server is set to an Open Directory Master. Now as for the client machine:
#1 - If I create both test users (local and network), will I be able to set the network as a Mobile Home Directory even though there is an existing home folder for the local user?
#2 - I want one specific user to have the same login name and password, but a different login "reaction" when the user logs in depending on the location. For example, I have a current network user Bob, password 1234 who is logged in and connected to the server. He finishes working on his project at the office and then goes home for the day. When he gets home, I want his to be able to login with the user name Bob, connecting to the local account on his machine. I DO NOT want to user PHDs, but rather have two separate home folders for the same resolving login user name! I know it is a lot to ask for but, here is my next question...
#3 - If I create two different home folders for the same resolving name, but they are accessed in two different locations, one with a server LDAP authentication and one locally (127.0.0.1), will it work?
I really appreciate the replies, but I am looking for more of straight forward answers rather than an example and background information. Thank you.

Two computers and two users with the same name. Can't copy files anymore...

Hi all, after a user migration to my new iMac I had to make a change of the shortname. I knew it was not a good idea but had no choice otherwise I had to wait other 3 hours to migrate data again...
Anyway, I managed to change my shortname with success, but one strange thing happened afterwards... I have two macs networked, both have an admin user with the same shortname/real name, 'gillo' (I followed the procedure in one of these two, the Intel iMac. The other, a Powerbook, was not modified).
While previously I had no problems in copying files from the user 'gillo' on the Powerbook TO the user 'gillo' on the iMac, after the shortname change I'm not anymore able to do it. The error I get is:
"The operation cannot be completed because you do not have sufficient privileges for some of the items"
Doesn't matter where I put the files, Desktop, Documents, even the Drop Box, I always get the same error.
I went through some checks and this is the 'log':
- The files/folders in the iMac 'gillo' directory are not locked.
- The files can be copied without troubles to the dirs of another admin user
- Permissions are the same as the other admin user and owner/group are the correct ones.
- Both Macs have 10.4.6
- The 'gillo' user on the iMac can copy files FROM the user 'gillo' on the Powerbook.
- I repaired permissions and the hard disk booting from the install DVD.
- I tried to change permissions of the directories (such as Desktop) on the iMac 'gillo' user allowing everybody to read/write. Also a no go.
Anybody went through this already? Or maybe something similar not directly related to the short name change?

Actually, everyone missed one point, when a device is priced, the cost of icloud storage space for that device is also included in it that is why they are able to give you 5gb each for each user ID, in nutshell there is nothing free coming with apple device purchase, it is paid for. What they are trying by giving only 5gb per user ID irrespective of the number of devices used is pure broadlight looting, they take money from you when you buy each device and give you nothing, This is a case of goods and services bought but not fully deliverd ie apple can be suied for discreminatory treatment towards it's users. I wonder why no one tried this yet in America where everyone sue everyone for petty things..... there is no one to take up this issue? . if tim got any love for the guys who shell out money for the devices his company makes, he should be implimenting this as priority before someone wake up from sleep and sue him.

There are multiple users with the same display name

Hi,
We have a user and when she get an item assigned to her she sees the following alert:
"There are multiple users with the same display name USERNAME and at least one of them does not have read permissions to some of the files"
Now I looked in the database and when I run the following query with the username:
SELECT
[ProviderDisplayName]
,[DisplayName]
,[HasDisplayName]
,[Domain]
,[AccountName]
,[UniqueUserId]
,[LastSync]
FROM [Tfs_Configuration].[dbo].[tbl_Identity] where displayname like '%USERNAME%'
Then I get 2 same usernames back, How can I get rid of one of them ? When I access TFS trough the portal I only find 1 occurence of this user.
We use VS2013 and TFS2013 update 4
Best regards

Hi DSW,
Thanks for your post.
In your query result, please check if these two users have the same Account Name. if they are two different Account Name in result, it indicate there’s two users have the same display name in your AD, please check that two users’ information in
your AD. We suggest change one user’s display name in AD.

Why do I see multiple users with the same name as an output of "users"

Recently, I found a peculiar thing when I typed "users" in the terminal. There were three users with the same name. After restart(power went down) I now see only one user there. Is this normal and why it can be happening? Why are there duplicate users sometimes?

alphaniner wrote:
Well now I'm confused. My xterm (xfce4-terminal) has that option disabled but I still get a user entry for each tab.
OT: you can run who to get a better idea of what each user is associated with. Eg. with Xorg on tty1 and terminal open with two tabs:
$ who
testing tty1 2013-12-11 08:55
testing pts/0 2013-12-11 08:55 (:0.0)
testing pts/1 2013-12-11 15:51 (:0.0)
Oh there is another option on mine besides "Run command as a login shell" called "Update login records when command is launched" I have them both disabled. Check for a second option maybe.

What's the problem with having multiple users with the same UID?

I've got three edit systems connected to the SAN using open directory off our server.
I want all edit systems to have read/write access to everything created. I don't need to protect anything from any of the systems. With all three systems logged on using the same user, I never have to change permissions.
The other cool thing about this is that Final Cut Pro will let me know if someone else is modifying a project that I have open with the warning:
“The project "projectName" has been modified externally. If another user is working on it, saving will overwrite their changes. Do you still want to save?”
This sounds great, right?
RED FLAG!!!! Apple gives the warning in this article:
http://docs.info.apple.com/article.html?artnum=302450
"You should not allow two users with the same UID to access an Xsan volume at the same time."
So why is it bad to have two (or more) users with the same UID?
I can see that in some situations it means that you can't prevent people from read/write privileges. But I don't want to restrict privileges.
What am I missing? With all of these warnings, it seems like if I do this my edit systems could all explode or something. Please help me understand the potential ramifications of having three users have the same UID.

Hi Russell,
1) If you have OD set up and "editor" has UID 1111, then when they log in to any machine that's bound to OD as editor, they will get UID 1111. Therefore, there won't be any of these permission errors. This is typically the recommended approach.
2) I assume you mean "You'd prefer to not using open directory?" Whatever the case, OD isn't mandatory with Xsan -- it's just that with multiple user accounts, managing them centrally tends to be easier. For 3 or 4 accounts and 3 or 4 machines maybe it's no big deal. If you go larger, it could get a lot more complicated. That said, if you set it up such that each machine has the exact same set of users (as you said, Mary = UID 502, Fred = UID 503, William = UID 504), then you can do what you want. Mary can log in from multiple machines at the same time, and in general you won't have permissions problems. Of course, if you try and read and write the same file from multiple workstations at the same time, you will get file locking issues, which will prohibit somebody from successfully writing the file.
File locking issues are different from general permissions errors. The former basically says "hey, someone else is editing this file. Therefore I won't let you edit it right now... you can read it if you want though." Permissions means somebody saves it, and Xsan thinks you saved it and own the file, when you really don't.

Is it possible to setup multiple users with the exact same calendar?

I am trying to setup exchange with 3 users where each user sees exactly the same calendar all precisely in sync. I don't need the users to have their own calendar. Sharing a calendar from 1 user to the others does not work for me because I need it to be
in sync with all the users' mobile devices as well as outlook.
Thanks

Hi dneray,
Base on my knowledge, it is impossible to setup multiple users with the exact same calendar.
However, as a workaround, you can try to set up a shared mailbox within these users as a shared calendar for them to share.

One User gets error Message saving an Incident, another user with the same rigthts not

Hi there,
We have a user sometimes getting an error message (see beyond) when saving an Incdient eg. only modified the descrition field. The user is able to create, update and resolve all other incidents. The user also may have changed this incident before.
When we use an other user with the same rigths, this user is allowed to modify the description field (and others)
We tested: The behavoir does not change for the first user, after the second user changed something.
It's not the workflow for the first assigned to date
No other user tries to use this incidents
We have a custom field, but it is not used in this case (so I know Romans SQL

Had a "powershell look" at the incident, but I did not see something "special" about this incident.
Anyone an idea, where to look at?

How to find login user with the largest account

Hello. I'm looking to put together a bash script that can do two things: (1) determine the shortname of the user with the largest account in /Users and (2) look up their full/long name. I'm going to use this script to help identify who the user on a computer and while I know that's possible that a sometime-user may have a larger account than the normal-user on any given computer, the results of a script should be sufficient in most cases for my needs.
I'm not sure the best way to around this. I know that I can use "du -m -d1 /Users" as root:
root on torchwood
[ ~ ]$ du -m -d1 /Users
157 /Users/admin
128 /Users/johndoe
70890 /Users/dancollins
21746 /Users/Shared
92920 /Users
I know that I can also use "dscacheutil -q user" to get a full list of all users on a system.
How can I get both the short and long name of the user with the largest account in the /Users folder?

We're running JAMF Recon for inventory and my supervisor wants to create a report that lists the primary user of the Mac... assuming that the largest user account may be the primary user. In this case, disk space is not the issue, the top admins simply would like to be able to associate names with individual machines. This isn't the most elegant way to do it and it's not fool-proof, but it'll be correct more often than not, which they're satisfied with.
Can I ask one more question? Using your script, I've started testing with one building and on a number of Mac, the "admin" (shortname) account is turning out to be the largest account. Is there a way to exclude the admin account from consideration?
Thanks...

Hi,
Per my understanding, the code should be OK, I have two suggestions as below:
1. Please ensure that the account of that user is valid in your production environment;
2. Try other accounts in the CreateUserProfile() funciton to see if it can work.
Feel free to reply if there any progress.

How to map the bulk users with the required roles in portal at one time

Hi,
Would anyone tell me how to map the bulk users with the required roles in portal at one time?

Thanks for all the reply.
<b>I need to assign 1 or 2 group to n((eg) 1000)number of users</b>
I tried the first option like
[group]
gid=
gdesc=
user=
Thr problem with this is I could n't put more no of users in the notepad.
I would be able to put only 150 users in the single line of notepad. If it goes to next line it is not working.
I tried creating seperate notepad but in Import it says "exists"
I'm not sure about LDAP. Would anyone explain me the best approach to do this.

Oh nice, there's a PassKeeper application for the iPhone and iPad. Simply install it and it should talk you through steps, otherwise their website is probably a great place to check.

Dissociate an end user with the primary device

I need to "Enable Mobily" for a new hire and I need to select his phone as the primary device. However, I run into this error: "Update failed. Device is already associated with another End User as Primary device"
Is there a way to dissociate the old end user with the primary device? As a last report solution, do you think that by deleting the phone off the CUCM, it will fix the issue when I add the phone back to CUCM?
Many thanks!
-Calin

Thank you George for your prompt response. :)
How would you "hunt down the other user" in order to make sure the phone is not associated with that particular user. We have about 3000 phones.
I checked the phone settings under "Device" - "Phone" and there is no user under "Owner User ID". Although, I think that this field "Owner User ID" is not connected in any way to Extension Mobility.
Thanks!

What happens to Apple Color users with the new Final Cut Pro x

What happens to Apple Color users with the new Final Cut Pro x?

Some of the functions of Color have been incorporated into FCP X, meaning you will have more than the 3-Way-Color-Corrector but less than Color.
Since you cannot share projects between FCP and FCP X, you might want to stay with FCS if you rely on Color.

We just received our new mac and took it to the store to have the old files from our last computer transferred over. Now we can't find all our files. There was more then one user on the old machine. How can we find the files from the other users?

We need to find where the files for the other user on the computer are now located. There were two other users on the old machine, which was taken into the store and ALL files were suppose to be transferred over to this computer. HELP!

It appears what happened is the installer though it was looking at a empty drive and just went ahead and installed.
I of course am assuming here you didn't use Disk Utility to format the drive first before installing, that would wipe out your files and programs for sure.
So what to do, what to do.
Well there is hope for you as long as the drive wasn't Filevaulted.
I'll explain. When a hard drive writes data for the first time to a drive, it starts at the very top and works it's way down.
When OS X was installed the first time, it was at the top of the drive, unless you upgraded then the upgraded OS X could have been written elsewhere.
Now when you just reinstalled OS X, the new OS went on the top of the drive, overwriting any data that was there previously, so what was there you have lost forever which is about 8GB or so. If it was the previous OS there, then your more in luck because only the old OS X was overwritten.
The remaining space on the drive still can have a copy of your files, provided it's not overwritten yet.
It's because when a hard drive deletes data or reformats, it doesn't remove the data off the drive or overwrites it immediately, it's just made so it's SPACE is available for new files to be written there.
So technically one can recover the deleted data off a non-encrypted/scrubbed hard drive with special software.
The way it does this is it reads the 1's and 0's of the files themselves, and through a lot of figuring out, can tell what that file is and what it belongs too.
So what you will have to do is this:
Create a data recovery/undelete external boot drive
or if you don't have the skills, then take it to a local PC/Mac tech and they can do a direct image of the drive and then you can run Data Rescue on it to rebuild your files.
