Custom EventReceiver Feature not appearing in manage feature list

Recently while deploying event receiver on one of the web application i faced a strange issue. My solution file got deployed successfully, but the feature was not visible in "Manage Site Features" of the site for which I have to activate the event receiver.

The web application was migrated from 2010 to 2013.

The web results returned from google search was not resolving my issue.

Since it was not available in "Manage Site Features" I tried to activate using powershell, using below command:

Enable-SPFeature -identity  -URL yoursiteURL

The command failed with error

The feature is not a Farm Level feature and is not found in a Site level defined by the Url [Site Collection Url].

Then google search for this error message, return the actual cause for the issue. While migrating site from 2010 to 2013, we have not done the visual upgrade of the site. And because of this the feature was not available in "Manage Feature List"

So the solution was to install wsp file with compatibility level.

Install-SPSolution -Identity "Solution.wsp"  –GACDeployment -CompatibilityLevel{14,15}

This resolved the issue, and feature appeared in Manage Site Features. Hope this helps.!!!!!

Connect SharePoint WebApplication to another domain after two way trust

If two way trust is already set. Then you can run below stsadm commands from your server:

Step 1:

First, you have to set an encryption key on all web servers in your farm so that the stored credentials can be encrypted:

Just to be clear, you have to run this on all web servers in your farm and the "AnyKey" value has to be set to the same value on all of those servers.

STSADM.exe -o setapppassword -password AnyKey
where "AnyKey" is any value.

For example,
STSADM.exe -o setapppassword -password B1gL0ngPassw0rd

Step 2

Next, you have to run below stsadm command to search users from other domain in people picker and give them access

stsadm -o setproperty -pn peoplepicker-searchadforests -pv "forest:DomainA.com;forest:DomainB.com,DomainB\login,password" -url "Your webapp url"

*DomainA: is a domain on which SharePoint installed

Domain B: is a new domain which you have to connect to sharepoint

Once above command runs successfully you will able to search users from DomainB in sharepoint portal which is on DomainA.

Hope this helps!!!!!
