Hi, Firstly, system info: Linux mysystem 2.6.18-53.1.4.el5 #1 SMP Fri Nov 30 00:45:55 EST 2007 x86_64 x86_64 x86_64 GNU/Linux I am running ldap on Centos with packages openldap-2.3.27-8.el5_2.4 y openldap-2.3.27-8.el5_2.4 I'd want to perform a query that return one attribute. So I did something as follows: ldapsearch -W -f qbis.ldif -D "cn=Manager,dc=palermo,dc=edu" -b "ou=people,dc=mydomain,dc=edu" -x legajo (Where legajo is the filter) There is no problem with filter but wih the file "qbis.ldif" which contains: dn: uid=jdoe,ou=people,dc=mydomain,dc=edu Of course I could perform that query with no need of one file, but I need to get "legajo" from around 800 users so it would be nice to be able to use "-f file". I cannot do something like a "loop for" because it would ask me every time the Manager password. Am I doing something wrong or is a ldap bug?
