Authentication Error

[Waqas Ahmed Khan]

I have installed Shibboleth IDP and its working fine with  SamAccountName
for IdP authentication. Now we got the request from management to switch
from using samaccountname in authentication to user’s email address.

I made these two changes in ldap.properties:

idp.authn.LDAP.userFilter= (mail ={user})
idp.attribute.resolver.LDAP.searchFilter=(mail=$requestContext.principalName)

But getting error "The password is incorrect". The password is correct and
working fine with SamAccountName.

*Error in idp-process log:*
