Webpart causing authentication error when cache is empty - showing just fine, when a lokal admin has

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :C#


I'm having some trouble with a webpart and some rights, I think.

I have created a webpart, showing some data from at database. Based on which Active Directory group the user is in, some part of the webpart is either show or hidden.

My problem is now, that every morning, the webpart causes an error, saying you need to logon. When I open the same page from the local machine with a local admin, the webpart shows up, and the webpart is now show as it should for everyone.
This behaviour happens next morning.

The webpart is deployed to the GAC.
I also sometimes se the problem when a user, who is in a group that enables them to se the "add comment" part of my webpart, they get the error, but the user, which are NOT allowed to se the "add comment" part see the webpart just fine.

I hope it is clear, what my problem is, but I will gladly try to explain deeper, what the issue is.

Error in / Application after adding employee search in webpart


Hello everyone,

I am working on sharepoint 2007 and I was editing the webpart of the software and after adding the predefined employee search table, the server has crashed while trying to access the server remotely with the following error message:

Error in / Application

However, while trying to login locally I have no problem and can easily login.

What will be the course of action in fixing this error.

Also the site is complaining of an invalid certificate even after adding an exception.

Any help would be greatly appreciated.

Thank You,

I've got a Windows 2008 SP2 server runing x64.

When i try to access the SharePoint Central Admin site, I just get a blank page. No errors in the Windows logs, nothing showing up in the SharePoint logs. The IIS log shows a 500 error.

SharePoint Calendar Error: The "ListViewWebPart" Web Part appears to be causing a problem. Index was

In one specific SharePoint calendar, on one specific week in that calendar when we select the "more items" link in the monthly view (or the expand all option) we get the following error:

Web Part working fine on the top-level page but 'Not Safe' error on lower-level pages.


I have created a Web Part which reads and parses the SharePoint logs in order to display usage information of the page it resides on.  The Web Part works perfectly on the top page, reading and displaying the information desired.  However, once the Web Part is added to any page lower in the site heirarchy (sub-page) the same Web Part throws the following error:

Web Part Error: A Web Part or Web Form Control on this Page cannot be displayed or imported. The type could not be found or it is not registered as safe.

Solved: LDAP authentication: error code 49 - 80090308, comment: AcceptSecurityContext error, data 52

Hi, I have a problem conneting to another domain (far.away.domain). We have a two-way trust to this domain. Also I can access the DS using ADSI edit and our Administrator account (ourdomain.com). I tried several types of credentials (userid = "CN=Administrator,CN=Users,DC=ourdomain,DC=com", "Administrator @ ourdomain.com" (without blanks)...). Connecting to ourdomain.com is no problem, but to far.away.domain I can't connect, I always get the error 525 (user not found). What could be the problem? Have I to use an entry from the ForeignSecurityPrincipals CN of the far.away.domain? I also tried to connect using Softerra LDAPBrowser and a command line ldapsearch without succes and with not a better error message. But why is it not possible to use a trusted account, or is this a active directory feature and does not work with pure LDAP bindings? Best regards, Nils.

The URL 'ao/AO Document/Admin Guideline/xxxxx.jpg' error on 2nd SharePoint server in farm

We just added a 2nd SP2007 server to mirror our site.  The original site is in China, the new site in the US.  They are connected via a permanent  site to site VPN.  We are hitting the errors when attempting to upload files to the US mirror.    Environment: US server site: OS: Windows Server 2008 R2 Enterprise (64 bit) APP: Windows Sharepoint Server 2007 Enterprise SP2 (64 bit) DB: Windows SQL Server 2008 Enterprise R2 (64 bit) China site: OS: Windows Server 2003 Enterprise SP2 (32 bit) APP: Windows Sharepoint Server 2007 Enterprise SP2 (32 bit) DB: Windows SQL Server 2008 Enterprise R2 (32 bit) Background: We setup two test Sharepoint farm to be syncronized with only its content database. The upload works good on SZ site. But we got the following 2 error messages randomly when uploading file to document library of SF side. Error message: 1. The URL 'ao/AO Document/Admin Guideline/xxxxx.jpg' is invalid.  It may refer to a nonexistent file or folder, or refer to a valid file or folder that is not in the current Web. 2. Cannot open file "ao/AO Document/Admin Guideline/xxxxx.jpg". -- We've tried the official hotfix, altering the schema, changing the IIS memory limit settings, and restarting the application pool. Could the issue be related to the different OSes 2008 vs 2003, or 32 vs 64bit?  

WCF REST webservice authentication error when hosted with godaddy

Hi guys, I'm currently hosting my site on a shared windows hosting box with Godaddy. I have upgraded my hosting account to .NET 3.5 and having IIS7 as well which is in integrated pipeline mode. I recently build a simple WCF web service using the REST started kit preview 2. Once i uploaded it to the server, I am getting this error"IIS specified authentication schemes 'Basic, Anonymous', but the binding only supports specification of exactly one authentication scheme. Valid authentication schemes are Digest, Negotiate, NTLM, Basic, or Anonymous. Change the IIS settings so that only a single authentication scheme is used." You can see it here:http://sawasdeethaiart.com/service.svcThe obvious fix for as i have read from various websites, is to make sure I configure my IIS to have either Basic or Anonymous specification enabled. But as i am on a shared hosting account, i dont have any access to do this. (I have checked all my options in the IIS hosting panel, but there is no option). I am also done this in my web.config<authentication mode="None"></authentication> Is there any other option I can add  to my web.config to overcome this? or is there any other fix for this? Any help will be greatly appreciated. Thanks,Mark  

WebPart has empty viewstate on postback

I have a simple weather web part in the form of a user control.  This usercontrol has an update panel and a textbox to allow the user to enter in a zip code/ city etc and an ok button.  The problem comes in when the webpart is added or dragged outside of Zone 1.  If this webpart remains in Zone 1 everything is fine.  If it is in Zone 2 or 3 after entering a zip code and hitting ok and posting back the value of the textbox is always blank.  It seems like the viewstate is cleared or the control is loading for the first time.  I have checked the Page.IsPostBack property and it is indeed True.  What would cause my control to loose the value entered in the textbox only when it resides outside of Zone 1?

JPEGS with empty IPTC / APP14 Tags cause GDI+ error

I am curious as to why the GDI+ libraries error our with exc = {"A generic error occurred in GDI+."} when the IPTC headers are empty.  I would assume it should reasonably take care of this.  I have taken am image and changed the "ff ed" app14 marker to more generic "ff ec" and everything loads fine and dandy.  So by analysis I am looking at a jpg the IPTC header has no data and I am guessing the GDI+ libraries dont handle empty data very well.  Anyone else having this problem.  Only workaround which is expensive is creating a new image and saving it to the stream which in a sense basically strips the header data making it more generic of an image.   System.Drawing.Image image = Image.FromFile("c:\\test6.jpg"); System.Drawing.Image image2 = null; ImageFormat format = ImageFormat.Jpeg; using (var stream = new MemoryStream()) { try { image.Save(stream, format); //using jpg with empty IPTC data will throw GDI+ error } catch (Exception exc) { image2 = new Bitmap(image);//this is expensive but gets job done image2.Save(stream, format); } context.HttpContext.Response.BinaryWrite(stream.ToArray()); } JPG Hex Bytes from beginning of file.  The Internal of the stream will error out about 24 bytes with a lengt

Grand Totals showing "Type MisMatch" error

Hi All, I have created a calculated measure using Exponential and Datediff function, and the formula is shown below. ( (EXP((DateDiff( "d", CDATE([Time].[Date].CurrentMember.PrevMember.MemberValue), CDATE([Time].[Date]. CurrentMember.MemberValue)))/365.0 * [Measures].[CD Dec Interest Rate]) -1) * ([Time].[Date]. CurrentMember.PrevMember.PrevMember,[Measures].[Cummulative_Premium])   ) In the above formula what i am trying to achieve is finding the difference between previous date and current no of days in days and dividing it by 365 and doing some multiplication after that, When i deployed above formula all my row values are getting displayed correctly but all my grand totals are displaying as "#VALUE" and when i checked the error, it displays as TYPE MisMatch. Could some one help me in finding the problem in above formula. Thanks in advance.

How do I get an error to stop showing up repeatedly?

I'm using a DatePicker in my WPF 4 app (my first WPF app).  This is meant to collect the date of birth of a client.  I've just this app out there for users to use, and the very first thing they did was enter a date of birth of 8/3/0983.  With the client standing right there in front of them.  Since it isn't likely that there's anyone alive today who is 1027 years old, I've got to put in a validation check. So I've been spending some time reading up on the best way to do this, and have come across the ExceptionValidationRule, which I've implemented.  Now, in conjunction with the class I've got that reflects the client's information, in the setting for the date of birth, I've got a couple of validation checks to make sure the client isn't older than is reasonable (yes, I know that's debateable, but let's not quibble over that now) and also make sure that the client's date of birth isn't in the future.  (One never knows what users may try to enter.)  I've tested it, and it works like a charm. But my problem is that, once my code detects that the user has entered an invalid value for the DOB, once the user corrects it, the validation check still thinks the value is wrong?!  Huh, how'd that happen, and how do I fix it, please?  Rod
