su error

[Robert Smol]

Hi, I am having problem with su - to another user.

root@czhs0681# su - ehealth
/usr/lib/dld.sl: Unresolved symbol: initialize_error_table_r (code) from /usr/local/lib/libkrb5.sl
Abort(coredump)

Can anybody help me to get over this? We do not use Kerberos at all. I remeber installing some KRB depot for CIFS server. I've attached core file.

[Steven E. Protter]

Shalom Robert,

Recommend running strings on the core file.

Also:

See that the pam configuration is not trying to block su to this user.

I'd also like to know that the PATH and SHLIB_PATH variables are normal on this machine.

what is there in pam.conf for su configuration? May be it is getting problem with kerberose configured su login. Check out.

thanks, for quick reply, here is /etc/pam.conf

strings on core file do show something like

!initialize_error_table_r

I would like to see where libkrb5 gets involved.

[Robert Smol]

Ha, when I invoke su -K (no kerberos) it works! can I disable it by default?

[Arunvijai_4]

Hello,

Kerberos 5 library should be from /usr/lib/libkrb5.sl or /usr/lib/pa20_64/libkrb5.sl. It shouldn't be from /usr/local/lib/libkrb5.sl.

Export SHLIB_PATH=/usr/lib:$SHLIB_PATH

problem SOLVED. Guys it was newbie problem. I have su installed in /usr/local (not sure where from) and PATH was set to /usr/local/bin.

root@czhs0681# ldd /usr/local/bin/su
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/lib/libdld.2 => /usr/lib/libdld.2
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/lib/libdb.sl => /usr/local/lib/libdb.sl
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/lib/libroken.sl => /usr/local/lib/libroken.sl
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/lib/libdb.sl => /usr/local/lib/libdb.sl
/usr/local/lib/libcom_err.sl => /usr/local/lib/libcom_err.sl
/usr/local/lib/libasn1.sl => /usr/local/lib/libasn1.sl
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/lib/libcom_err.sl => /usr/local/lib/libcom_err.sl
/usr/local/lib/libdes.sl => /usr/local/lib/libdes.sl
/usr/lib/libc.2 => /usr/lib/libc.2
/usr/local/lib/libkrb5.sl => /usr/local/lib/libkrb5.sl


so here comes the libkrb. Once I used HP su at /usr/bin, problem disappeared.

Thanks for support.
