ssh doest not trigger source .bash_profiles

04.5 LTS. A server admin create my account, but it is little bit different with what I know. It seems like ssh does not trigger source $HOME/.bash_profile`.

I think the account is not completed somehow.How can I examine the problem

symptom:

• .bash_profile does not work
• source: not found
• unable to auto-complete by tab key
• prompt starts with $, not [user@localhost ~]$

How can I fix this account?

===== UPDATE =====

it comes out that login shell was not bash

$ echo $SHELL/bin/sh

Can I set ssh to bash shell for a specific account?

Do not want to any side effects for other accounts or rebooting system or sshd service.
