Problem in adding external user with FBA

The forms-based authentication (FBA) provider supports authentication against credentials stored in Active Directory, in a database such as a SQL Server database, or in a Lightweight Directory Access Protocol (LDAP) data store such as Novell eDirectory, Novell Directory Services (NDS), or Sun ONE.

I had issue with form based authentication i get the below error when try to add new external user to SharePoint group.

The user or group '' is unknown.   at Microsoft.SharePoint.Utilities.SPUtility.FilterValidLoginName(String loginName, SPSite site) 
   at Microsoft.SharePoint.SPUserCollection.FilterConvertSPUserInfoArray(SPUserInfo[] userInfoArray) 
   at Microsoft.SharePoint.SPUserCollection.AddCollection(SPUserInfo[] addUsersInfo) 
   at Microsoft.SharePoint.ApplicationPages.AclInv.BtnOK_Click(Object sender, EventArgs e) 
   at System.Web.UI.WebControls.Button.OnClick(EventArgs e) 
   at System.Web.UI.WebControls.Button.RaisePostBackEvent(String eventArgument) 
   at System.Web.UI.WebControls.Button.System.Web.UI.IPostBackEventHandler.RaisePostBackEvent(String eventArgument)

   at System.Web.UI.Page.RaisePostBackEvent(NameValueCollection postData) 
   at System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint)

Most of time fix to this kind of issues is correct configuration of Authentication Providers in Central administration. Same worked for me too. I followed the below two links to resolve my problem:

Issues faced while upgrading SharePoint 2007 to SP2

Hi friends, upgrading SharePoint 2007 to SP2 was not an easy task for me. I almost spent more than a week to fix all the issues occurred. I am sharing my findings so you will know what kind of issues can come and how to resolve them.

Note:- Before you start the installation, you must get the correct service packs/cumulative packs  and install in correct order (install first WSS and then SharePoint SP2). After installation, you will be asked to run the SharePoint Product Configuration wizard. That is the area where your fight will start with SharePoint. Below i have list down the issues i faced and solutions as well. 🙂 For me update always failed at step 8 (seems to be big important step).

Note:- Keep your eye on event log and find for error keyword in log file generated after configuration failure. Upgradelog.txt file contain all the error details and present in “c:\Program Files\Common Files\Microsoft Shared\web server extensions\12\LOGS” directory. Search for error count at bottom of the file (e.g. 1 errors and 0 warnings encountered.). This file is the main source and guide us to fix all issues.

Issue 1 – Unable to start the SharePoint Search service. Error was log on failure. To fix this issue you must check the service account try to run the service during configuration wizard. It uses the account which you have used to setup the SharePoint server. To reset the account click here

Issue 2 – After fixing above issue, i ran into another one. Below are the error details from upgrade.log file.

[SPManager] [ERROR] [7/18/2011 3:36:22 PM]: Pre-Upgrade [SPSite Url=http://ServerName] failed. Microsoft.SharePoint.Upgrade.SPSiteWssSequence has the ContinueOnFailiure bit set. Moving on to the next object in sequence.
[SPManager] [ERROR] [7/18/2011 3:36:22 PM]: The system cannot find the path specified. (Exception from HRESULT: 0x80070003)
[SPManager] [ERROR] [7/18/2011 3:36:22 PM]:    at Microsoft.SharePoint.Library.SPRequestInternalClass.GetSiteQuota(String bstrUrl, UInt16& pdwQuotaTemplateID, Int64& plDiskQuota, Int64& plDiskWarning, Int32& plUserQuota)
   at Microsoft.SharePoint.Library.SPRequest.GetSiteQuota(String bstrUrl, UInt16& pdwQuotaTemplateID, Int64& plDiskQuota, Int64& plDiskWarning, Int32& plUserQuota)

   at Microsoft.SharePoint.SPSite.get_Quota()
   at Microsoft.SharePoint.Upgrade.SPSiteSequence.PreUpgrade()
   at Microsoft.SharePoint.Upgrade.SPManager.Upgrade(Object o, Boolean bRecurse)

I removed the web application and started the configuration wizard again and it worked fine. (Note: I removed the application because it was empty and in my development environment. But this not be the case all the time. We must find the root cause with the help of error message and fix it.)

How to start the WSS Search Service via Central Administrator

When you stop and start the WSS Search Service in Central Administrator (Operations=>Services on server=>Windows SharePoint Services Search), you may get the following error:

Database_name contains user-defined schema.  Databases must be empty before they can be used.  Delete all of the tables, stored procedures and other objects or use a different database.

Follow below steps to fix this issue:

Step 1 – Stop SQL Server service

Step 2 – Delete files WSS_Search_ Servername.mdf  and WSS_Search_ Servername_log.LDF

Step 3 – Start SQL Server service

Step 4 – Restart the WSS Search Service again (Provide new name for search database, old database name might not work.)
