RE: 'unary operator expected' error when TLS turned on - SOLVED

Adding the 'set -x' option top of /etc/profile, I was able to determine the culprit of the

"-bash: [: =: unary operator expected"

error that has been occurring on all Linux servers since turning on LDAP TLS on INT.

In the file:

/etc/profile.d/krb5-workstation.sh

The follow is causing the issue:

if ! echo ${PATH} | /bin/grep -q /usr/kerberos/sbin ; then if [ `/usr/bin/id -u` = 0 ] ; then PATH=/usr/kerberos/sbin:${PATH} fi fi

If I add " " around the backticked command, I the bash error goes away.

Not sure who I need to open a ticket against :-)

Thanks, John

I've also posted this message on the OpenSSL forum:

I just turned on TLS on my LDAP (per instructions on http://www.openldap.org/faq/data/cache/185.html). Now all of my Linux servers (RH EL5) give the following error on login:

-bash: [: =: unary operator expected

The error goes away when I turn TLS off. I cannot determine what is causing this error, or even which file contains the error. I've gone through my LDAP config files, cannot find an issue in any of these.

Other than my cacert.pem, and the LDAP config files, are there other files that are read only when TLS is turned on?

Thanks, John

I am running Openldap 2.3.43-2.el5 & OpenSSL 0.9.8b-10.el5 (RPMs from Red Hat, which I am required to use unless I put up a BIG fight).

++++ Here's my configs ++++

I turn on TLS by adding the following in my /etc/ldap.conf (pam/nss file):

ssl start_tls tls_checkpeer yes tls_cacertfile /etc/openldap/cacerts/cacert.pem tls_cacertdir /etc/openldap/cacerts/

and have the following in my /etc/openldap/ldap.conf (openldap file):

HOST 172.25.3.97 BASE dc=example,dc=net TLS_CACERTDIR /etc/openldap/cacerts/ TLS_REQCERT allow

and my (self-signed) cacert:
