help: some shell can not run su command?

[ferry_4]

modify user's login shell through edit /etc/passwd ,not SAM. There is ok to telnet to the machine for these users, but they can not run su command. the error message is following:
/usr/lib/dld.sl: Can't open shared library: /usr/local/lib/libcom_err.sl
/usr/lib/dld.sl: No such file or directory
But these user can run su command through xwindow.
What's the reason? How to solve the problem?

Hi ferry,

Please give us the output of the following command, when executed in xwindow and the other on telnet session.

the command is,
which su

Is there anyconfiguration in /etc/pam.conf file su regardless of default configuration. That is making problem.

# grep su /etc/pam.conf

post this or check this.

Hi Ferry,

What is your SHLIB_PATH and LD_LIB_PATH ? Try to check from telnet,

# ldd `which su`

hi senthil,
normal user's su: /usr/bin/su
question user's su: /usr/local/bin/su

I can't imagine why there would be a "su" in /usr/local/bin unless you've been hacked. I would get rid of it.

Hi,

There shouldn't be any question user's su: /usr/local/bin/su .. Change it to /usr/bin/su

Tt's very surprising that su is ok in xwindow session which su at /usr/local/bin/su , but su is error in telnet session which su at /usr/local/bin/su.
It's ok if I type /usr/bin/su to run su command.
What's the order of the $PATH search?

[Arunvijai_4]

Hello,

Just check PATH variable..

# echo $PATH and check the order in both X and telnet session.

Hi ferry,

Just make sure, in the file /etc/PATH file /usr/bin directory appears before /usr/local/bin.

Or work with the $PATH variable in /etc/profile file till "which su" command in both xwindow and normal telnet session yields the same result namely, /usr/bin/su

Try to change the PATH variable configuration. IT will get the binaries based on that. Change the configuration with /etc/profile as,

export PATH=/bin:/sbin:/usr/bin:/usr/sbin: like that but. /usr/local/bin has to come after /usr/bin. Try to see /etc/PATH file also.

If you have not explicitly configure DTSOURCEPROFILE=1 /etc/profile file is not read.
