Taking a look at your bostoncoop account, you've got some weird going on:
bostoncoop:~>ls -al /home/ntrivedi
drwxr-xrwx 28 ntrivedi ntrivedi 4096 Jul 12 12:13 .
drwxrwsr-x 54 root staff 4096 Jul 9 23:53 ..
=2E...
The first line there means that your account is world-writable. I.e.,
anyone on bostoncoop can write to your directory.
Looking at the bostoncoop error log (/var/log/auth.log), I see:
Jul 12 13:58:50 bostoncoop sshd[21445]: Authentication refused: bad ownersh=
ip or modes for directory /maxtor/home/ntrivedi=20
I think ssh is refusing to recognize your key because security has been
compromised; your home directory is world writable. No good.
You can change it by logging into bostoncoop and typing:
chmod o-w .
This takes away world write permissions from your home directory. You
could also do:
chmod o-rw .
Which would take away read and write permissions from the world from your
home directory.
I'm not sure how your directory got that way, but it's a bad way to be.
