Hi list, I'm having a problem in using the example back_shell example of OL distribution.

I'm using OL 2.4.21 as released in Ubuntu10.04 distribution.

This is my database definition:

database shell suffix "dc=pippo,dc=it" search /tmp/slapd_search.sh

This is the example script found in the OL distribution. Im my test this is /tmp/slapd_search.sh

# result echo "RESULT" echo "code: 0"

exit 0

This is the result. I cannot see my user listed

root@LTSP-vanilla:/etc/ldap/slapd.conf.d# ldapsearch -v -x -s sub -b "dc=pippo,dc=it" "(cn=marco)" ldap_initialize( <DEFAULT> ) filter: (cn=marco) requesting: All userApplication attributes # extended LDIF # # LDAPv3 # base <dc=pippo,dc=it> with scope subtree # filter: (cn=marco) # requesting: ALL #

By using strace I can see full execution appering. This is the final excerpt of my output:

As you can see with bold font, I obtain a strange behaviour "fgets failed". But user "marco" exists in /etc/passwd. Someone could tell me what is wrong?

Thanks in advance Marco
