dumb bash_profile question

[Craig White]

I have a problem with 'ingres' user which I have a home directory within
a deeper tree.

When I 'su - ingres' the current working directory is indeed the ingres
users home directory but the .bash_profile (644 perms) doesn't get
loaded and while I can manually 'source' the file to load it, it really
needs to be automatic. What issues might be stopping that from
occurring?
