Restrict use of special characters in AD usernames

I am planning to restrict use of any special characters including - "dash" when creating AD users in ADUC console.
All are windows server 2008 R2 Domain Controllers
Any suggestions.

You should change the thread to a question rather than discussion.
My recommendation would be to use PowerShell to do this.
You could edit this script
http://gallery.technet.microsoft.com/New-User-Creation-tool-14fa73cd
It will give you a GUI interface and you could edit this to prevent the characters you want from being used in usernames.

Disable use of special characters in a form

We are wanting to disable the use of special characters that are not in the font family already. Arial Unicode has an expansive family, where Roboto doesn't. Is there a simple way to do this?

I think I've already replied for this on the other post.
Check the link that I've posted in it.

Special Characters in a username cause login problem

We have got SSO setup on our application and have successfully been testing away, until we tried logging in with an account which has a '+' character in the username. We are authenticating and getting an SSO token but the login process then fails with a "User has no profile in this organization" message. This call http://forums.sun.com/thread.jspa?messageID=9820513 talks about a workaround that ignores the Profile service which does get us logged in, but in the longer term I need to be able to use this functionality to set conditions per URL policy.
Has anybody come across other probelms with usernames containing special characters? Is there some kind of encoding switch I need to turn on somewhere.
Cheers and TIA for your help.

Use of special characters in Search String

What is the use of special charaters like
in the search string in the Find & Replace of ABAP editor ?
I want to search for all strings starting with V which are followed by alphabets like
VA
VB...
If I use V*, it also gives me results like
V/R...
Whether it is possible to specify such a condition?

Hi,
While giving ur search in FIND & REPLACE,
use the match case or match whole word only..
Then u will get search results only where the exact case of that variable is used..
As per my knowledge there is no signification of special characters ,- : ; in the search string..
Hope this helps...
Cheers,
Simha.

Using accents/special characters in keyboard WAY TOO SLOW!

I'm often using french, and thus many words have many accents (just a short phrase exemple : l'été passé j'ai dû boire l'amère potion de la déception... A short sentence, 5 accents. Can be worse).
I'm typing pretty fast, and already getting frustrated because the french keyboard doesn't have the ' included, which would save so much time in contractions. (Would probably be added automatically if I could use the corrector, but I can't, cause switching from french to english all the time, I just get stupid jumble all the time).
But the worst of the worst is each time I need to type an accented letter, I lose 2.5 seconds! Because that's how long it takes for the accents options to pop-up after I hold my finger on the letter...
It's completely ridiculous!
Typing a short 3 letter word like "été" takes over 6 seconds!
It makes me so mad!
I almost completely stopped writing my french emails or Facebook updates and such from my iPod Touch and prefer to wait until I'm on my MBP! Is that normal when you have the chance to own the Touch?!
I've contacted Apple about this many months ago, but like any complaint I've had in the past, never heard of them.
Has anyone else have such a delay with the accents/special characters keyboard (popups)?
Is there something I can do?

Simply copy and paste. Just did it and it worked. Perhaps I'm not understanding something. What do you mean by "insert a font."

Special characters(Apoostrophe) in username

Hi
weblogic server (10.2) does not seem to allow users to be created with an apostrophe(') in the user name. If a user already exists in the database , the SQL Authenticator refuses the login as well (even if the password is correct).
is there any workaround/patch for this problem?
Also what characters are not allowed?

Some code validates that the login name doesn't have apostrophe (which is silly because the authenticators use PreparedStatement).

I use some special characters (vowels with an accent mark), these are not showing up properly, whereas they do on my old IE browser-can anyone help?

Here's an example. The Irish word "Lúnasa" is showing up as "L�nasa" when I post it in places such as Yahoo! Groups. This does not happen with my old IE browser. Thanks for any help!

No, the first "Lúnasa" looks correct. The second one is how it appears after posting it to a Yahoo! Group. It's odd, because when I view the same post in the Yahoo! Group via IE8, it looks fine. Just to fill out the details, I wrote the original "Lúnasa" in MS Word, then copied and pasted it into my Yahoo post. Needless to say, I am confused!
Thanks again for you help!

802.1X PEAP fails when using special characters in login

I am using MS AD & NPS for 802.1X Enterprise authentication with PEAP (no client certificate - MS-CHAPv2 user credentials for login). This works fine for iOS devices on 8.1 (iPhone 5 and iPad mini) and 6.1.6 (iPhone 3GS) when the user has standard "English" ASCII characters in the username and password.
However, when I introduce Unicode special accented characters in the login name or password such as French é/ù or Spanish ñ then after accepting the server cert authentication fails with "Incorrect username or password for <WLAN name>". Windows 7 and CentOS 6.5 laptops have no problem authenticating to the same setup with either "English" credentials or ones with special accented characters. I also tried an old iPod touch on ancient software version and that fails, so its not something recently introduced.
I tried using a different access point (TP-Link instead of Ruckus) and had exactly the same issue, so highly unlikely this is an AP issue.
Then I setup FreeRadius with and see exactly the same issue, so its highly unlikely to be a MS AD/NPS issue.
When comparing a working/failed authentication Wireshark packet capture on the NPS server, I see the failed attempt is missing the last 4 packets in the authentication exchange. The last packet sent is an Access-Challenge from the NPS server and no response from the iOS device, so the NPS server never even sends an Access-Reject. The iOS device appears to have decided it can't resolve the special characters and terminates the authentication attempt.
To me this seems to be an Apple iOS software deficiency when using Unicode special characters in the username or password for 801.2X authentication?

OID/Portal - Restrict Special Characters to be used in Password

Hi,
Does anyone know how I can restrict the use of special characters ($, &, £...etc) in the OID password? I cannot see an attribute to achive this? orclpwdIllegalValues will stop certain words, but I just want to restrict the use of any of the special characters in any password. All suggestions or information would be much appreciated.
Thanks

Requires custom plugin (using PL/SQL) to add password value checking to OID password policy management capabilities. A description and example code for this is available in chapter 27 of the Oracle® Internet Directory Administrator's Guide, 10g Release 2 (10.1.2) entitled "Oracle Internet Directory Plug-In for Password Policies" available at http://download.oracle.com/docs/cd/B14099_19/idmanage.1012/b14082/plugin_pwdpolicies.htm#i122359

Use special characters in a DTD

Hello,
I created a DTD amd want to use some special characters in this DTD. E.G. I want to define:
<!ATTLIST element value (val1|val 2|<val3>|%val4) #REQUIRED>
I tried the following but the parser does not accept without errors:
<!ATTLIST element value (val1|val&#xxx;2|&#yyy;val3&#zzz;....
Of course I replaced the xxx, yyy and zzz with the unicode number of the special sign.
So what do I do wrong? Or is it in general not possible to use special characters ?
Thank you very much,
Findus

Hi,
one thing I did which does not work is:
<!ATTLIST element values (&|<|val1) #REQUIRED>
The XML parser (XMLSpy) alway requires me for entering a '%' which is as far as I know only used for parameter entities. But & and the rest are general entities, aren't they ??
I played arround a little bit and found a solution which still does not completly solve my problem: In order to use special characters I declare parameter entities:
<!ENTITY percent "%">
<!ENTITY lower "<">
<!ATTLIST element values (%lower;|val1|%percent;) #REQUIRED>
This works so far so good but if I want to embed the special characters (which is what I need to do!) the parser still gives me errors:
<!ATTLIST element values (text%lower;moreText|val1|%percent;) #REQUIRED>
I would be really glad if anybody could test this on his own and post me about the results. For any other kind of avice I'm very thankful, too.
Thank you very much,
Findus

Why can't I use special characters in my password? This isn't 1995 anymore where a lot of people don't have QWERTY keyboards.

Why does your site not allow the use of special characters in passwords? Do you not want your customers to be as secure as possible?
As a network security admin, limiting passwords to prohibit special characters is an extremely poor security practice.
Telling me that my security as a customer is important, then tell me that your own system limits my ability to keep my account as secure as I would like seems quite backwards. I understand the archaic reasoning was that not all devices have a QWERTY keyboard, this logic is flawed and is no longer necessary.

Hi, sorry to hear that you are experiencing these problems, but sometimes a new machine (be it Apple, Dell, whatever) can be defective right out the box - its not unheard of.
If your machine came with defective hardware and is still under warranty (seems to be the case here) then you have nothing to lose taking it back to where you bought it and, if there really is defective hardware present I am sure they'll rectify the problem.
A small note: these problems are not manufacturer-specific - its pointless blaming the manufacturer as I can assure you this happens with ALL brands. Apple supplies quality hardware and software - I know of a user who has had a machine switched on since 1987 without problems

Special characters in file name of attachment...

Hello,
I attached a file in SC which had # in the file name. I was not able to open the attachment... Is there any restrictions on using the special characters in attachment file name?
Regards
Amit

Hi. Yes, we had the exact same thing. If the file name is not A to Z or 0 to 9 it can not be opened.
I think we asked SAP and there was no solution for our system.
I think it depends on your file system and things like that though.
Regards,
Dave.
