  Re: any one can explain Self mapping Delegation Remote Credentials
Answer
# 1
These are the three different security model connecting to 
Linked Server. 

In Self Mapping SQL Server tries to connect to the linked 
server using current users credentials(UserId and PWD).

In Delegation SQL Server tries to connect to the Linked 
server by using the Windows credential.

In Remote Credentials the Local login credential is mapped 
into remote credential.
