am i insane?
 

what have i done to make bash start complaining "permission denied" whenn ever i try to su username? I used to be able t o switch users in any directory (not view only switch) w/out complaint. Now i get permission complainds even in users home directory. Any help would be greatly appreciated.
thanx

[root@linux jacob]# pwd
/home/jacob
[root@linux jacob]# su jacob
bash: /home/jacob/.bashrc: Permission denied
bash-2.05b$

# .bashrc

# User specific aliases and functions

# Source global definitions
if [ -f /etc/bashrc ]; then
. /etc/bashrc
fi
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi
