We're still setting up our Isilon and getting ready to migrate data, and I've been trying to get LDAP authentication working even though we're not planning to use LDAP at this time (we'll be using NIS to start, then AD at some point, and both are working as expected right now). I have a case open with Support and they assisted with some of my initial LDAP issues, but so far not with this "Email Address" field issue and this is sort of bugging me because this is the one field that should be really straightforward and mostly standard.

The problem is that the "Email Address" field part of User Information never has a value no matter what attribute I set up in Advanced LDAP Settings for "Email Attribute".  We certainly do have the 'mail' attribute available and readable by the account doing the bind, but Email Address for every user is always "No value".  In troubleshooting, I made EVERY attribute 'mail' that I could (UID and GID are the only exceptions since they throw errors when using 'mail') and I can see the user's email address as the User Name, Full Name, Home Directory and SAM account name.  But Email Address is still No Value.  Can anyone explain why I'm seeing this or confirm that it is working for you?  I can't find any documentation that specifies exactly what "Email Attribute" in Advanced LDAP Settings is but common sense suggests that field would map to Email Address, yeah?  See pics below:
