Re: [squid-users] Authentification against DominoNotes LDAP

When executing commands from the command line shell both & and ( is
special characters and need to be within quotes. Also, LDAP does not
make use of quoting.

Try this slight variation of the same command:

ldapsearch -h 172.25.0.19 -p 389 "(&(member=CN=Stefan
Vogel,OU=nu,OU=eu,OU=au,O=cag)(cn=CAS_NU_Internetuser))"

The point is not that the two objects are different, the point is what
each object contains and how this translates to search filters. A LDAP
filter can only match a single object. A search filter for looking up a
user object is different from a search filter user for looking up if a
user is member of a certain group, because the objects the two filters
looks for is fundamentally different in their content and structure.
