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.

What is the purpose of having 'oracle' user with umask 022?
Hello,
What is the purpose with having the 'oracle' profile with a umask of 022? Isn't that a security risk having files created by 'oracle' with 755 permission? I mean why let others have the capability to read and execute on files that 'oracle' writes. Thank you.
PaulHi;
You can set it as you wish. But from note:
The umask utility sets the file mode creation mask of the current shell execution environment to the value specified by the mask operand. This mask affects the initial value of the file permission bits of subsequently created files. If umask is called in a subshell or separate utility execution environment, such as one of the following:
+(umask 002)+
nohup umask ...
find . -exec umask ...
it does not affect the file mode creation mask of the caller's environment. For this reason, the /usr/bin/umask utility cannot be used to change the umask in an ongoing session. Its usefulness is limited to checking the caller's umask. To change the umask of an ongoing session you must use one of the shell builtins.
If the mask operand is not specified, the umask utility writes the value of the invoking process's file mode creation mask to standard output.
The most common umask values are 022, 027, and 077. A umask value of 022 lets the owner both read and write all newly created files, but everybody else can
only read them:
Oracle recommended(also its a prereq for installation) to set umask 022 due to do upper explanation.
http://docs.oracle.com/cd/E19253-01/816-5165/umask-1/index.html
Regard
Helios
Source:
+0666 Default file creation mode+
+022 resultant mode+
+0644 resultant mode+
On many UNIX systems, the default umask is 022. This is inherited from the init process, as all processes are descendants of init. -
The event library and multiple users in the classroom
Is there any way I can stop the event library loading old footage or footage from another project in imovie. Is there any way i can have 3 or 4 movies on the go in separate files.
I have ten macbooks for my class of thrity kids. We have two users on the computer Admin and Student. All students use the student side, every time imovie opens it gets old footage and events from iphoto and by the end of each term there is 8 to 10 gigs of footage on the go at any one time. imovie HD allowed save, file open and movement of movies. imovie 08/09 seems brilliant for snow boarders and you tubers but not the classroom. Really we would love an editing package that allows attachment of camera and work for a couple of weeks on a project while others do the same thing on the same mac. Please don't suggest multiple users we have over 200 macs and 600 students.Without multiuser, the only of having an exclusive event library for each student would be either external drive, or a blank disk image to store iMovie events. I can imagine a large network drive that has 50GB size disk images for each students. You mount your image to work with your footage.
By the way you can move event library to other drive within iMovie, so you can back up and disconnect external drive to unclutter event library. -
Lots of info about one user using multiple computers. What about multiple users with separate Apple IDs using same computer? Having problems getting my wifes new iPhone talking to her apple account on the computer we share (2 users)
You need to create a user account for your wife (or yourself depending on who has the current user account). When syncing, each of you should sign in as a separate user, login to iTunes and then sync. I had this problem when my sister got an iPhone. When we did her initial sync, everything on my iPhone showed up on hers. Apple gave me this solution.

Hi! I am so stumped with having multiple Apple ID accounts. I did this not knowing what I was doing and now I can not update my iPhoto app because it tells me to log into the account that I used to purchase it. I thought I was trying to do this but I can't get anywhere.
Please help!

I'm having problems with iPhoto and the facebook set-up. Every time I attempt to do so it says an error has occured and try again later. I have not seen a solution posted. Therefore, how does one contact Apple to solve the problem? I'm new to the world of iMac but I find it a bit frustrating trying to solve basic issues/problems:(
For what it's worth, you posted this in 2011, and here in 2014 I am still having this same issue. Over the last two days, I have had to unlock my apple account 8 times. I didn't get any new devices. I haven't initiated a password reset. I didn't forget my password. I set up two factor authentication and have been able to do the unlocking with the key and using a code sent to one of my devices.
That all works.
It's this having to unlock my account every time I go to use any of my devices. And I have many: iMac, iPad, iPad2, iPad mini, iPhone 5s, iPod touch (daughter), and my old iPhone 4 being used as an ipod touch now. They are all synced, and all was working just fine.
I have initiated an incident with Apple (again) but I know they are just going to suggest I change my Apple ID. It's a simple one, and one that I am sure others think is theirs. I don't want to change it. I shouldn't have to. Apple should be able to tell me who is trying to use it, or at least from where.
Thanks for listening,

What is the point in having multiple columns in ORDER BY clause?
DB version:10gR2
When using ORDER BY clause, the rows are always sorted according to the first column in the ORDER BY clause. So, what is point in having multiple columns in the ORDER BY clause(i always see this in production codes)?
For the below SQLs' from SCOTT schema, the result sets are always ordered according the first column ename. When i added job asc and job desc, the result set doesn't change.

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 regardsHi 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.

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.
ThanksHi 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.

although we have iphones and ipads, this is our first imac and we wanted to know the best ways to set up multiple users with parental controls
I'm assuming you have the lastet OSX version 10.9 "Mavericks." Here are some useful links from Apple I think will help:
http://support.apple.com/kb/PH14414
http://support.apple.com/kb/PH14099
http://support.apple.com/kb/PH14280
and a video:
http://support.apple.com/kb/VI28
I suspect you have a newer iMac than the pre-2006 models this forum covers (the forum labels are unbelieveably vague). If you can confirm that yours is newer than 2005, I can ask the Hosts to move you the the forum for current iMacs, which gets many more views. -
Multiple users with the same iPad?
My daughter has lent me her iPad. It's currently linked to her Apple account. If I try registering the iPad on my Apple account, will I be violating the license or screwing up her ability to use the device independently? Can the iPad work independently with two seperate users with two separate Apple accounts?
if you are registering your own apple id over your daughter, her account wont be able to put back in for at least 90 days. iPad will notify this fact, you this whenever you try to enter new apple id in the existing user ipads.
another way that would help is to home share your itunes content and allow photo stream features on the ipad, so you will get your contents into your daugther ipad without entering your apple id.
ipad cannot work with two user. you wont be violating any license. -
Multiple users on the same ODI installation?
Hi all
is it possible to have multiple users working with the same odi installation? We have a virtualized IT infrastructure (citrix and wmware) where we can have multiple users on the same virtual instance. From our point of view, there is no licencing issue since we have a package covering literally everything.
One of the issues are the config files stored in the installation directory of odi (../bin). Is there a way to tell odi to store them in a different location, eg. the user home?
Thanks a lot
BennoODI looks in the current working directory for the configuration files, mostly you would have issues with the snps_login_work.xml and snps_login_security.xml files, but these may be common across all users. (just don't store the username/passwords for the ODI users in them).
The way ODI works, most of what are creating is stored in the repository anyway, it is only local GUI config stuff that may be stored locally.
Short answer, yes, you can, but might need to modify the config files a little to make it work. -
WebTools Creating multiple users for the same User
I had to make a few changes to a BP in SAP which will synch back into WebTools but now I am getting multiple users for the same contact. For example my user is cspehar_1 now in Webtools there are cspehar_1, cspehar_2, cspehar_3 and so on up to _8.
This is occuring for several users in webtools.
What causes this and how do I fix it?
Thanks,
Craig SpeharHi Craig,
There are two ways to cause this that I am aware of:
1. Change the "Business Partner Synch Contacts Field" setting after the initial synch.
2. Change the Web UserID on the BP contact in B1 (OCPR.U_PRX_SID).
After that, update the user in WT and synch. (might also happen if you update the BP in B1)
Since the synch is using the OCPR.U_PRX_SID to identify the contact, it will not be able to find it in B1 if the U_PRX_SID has changed. When it does not find it, it assumes it needs to be created. This results in a duplicate.
The solution is to reset the U_PRX_SID back to what it was or set the synch contact field back to what it was.
Then delete the last created duplicate contact from B1.
There may be further data corruption issues here. If orders/quotes/opportunities or other dependant data has synchronized referencing the duplicate user, these data will need to be correct as well.
FYI, whatever caused this was probably at the root of your order problem as well.
Maybe you are looking for
