The security validation for this page is invalid - resolution



Whenever you are having your code trying to manipulate files in document libraries and they have to work in different identities, you most properly will have your "Allowunsafeupdates=true" line added in your code. This works most times, but at certain scenarios, it might throw up the below error (at the time when the code is trying to move a document from one library in one site to another library in another site). The same code however would have worked for the Admin login.

Resolution
The resolution for this is not in the code unfortunately! All you need to do is go to your Central Administration -> Application Management -> Web Application general Settings and turn off the "Security Validation"

Bingo, your code for all users starts working fine!

For example, if your SP's Input Parameter is @Emp

When trying to connect to the database in classic client I got this error. The following SQL server error or errors occurred: 17750,“42000”,[Microsoft][ODBC SQL Server Driver][SQL Server]Could not load the DLL C:\Program Files (x86)\Microsoft Dynamics NAV\60\Database\xp_ndo.dll, or one of the DLLs it references. Reason: 193(failed to retrieve text for this error. Reason: 15100). SQL: INSERT INTO [#$ndo$groups] {CALL [master]..[xp_ndo_enumusergroups](?,?)} The reason for this error is that the installed xp_ndo.dll is 32 bit and not 64 bit. My solution was simple to replace xp_ndo.dll with the 64 bit version. 1. Stop SQL server 2. Copy \\vedfssrv01\DynamicsNAV2009\W1\DVD\Sql_esp\x64\ xp_ndo_x64.dll to C:\Program Files (x86)\Microsoft Dynamics NAV\60\Database 3. Rename existing xp_ndo.dll to xp_ndo_x32.dll 4. Rename xp
