install the ldap-utils package - that one containing ldapsearch - and 
execute:

ldapsearch -W -D cn=admin -b 'dc=[domainname],dc=de' \
'(&(objectClass=posixAccount)(uid=<<uid>>))'

then enter your password.

1) I suppose, cn=admin is missing a domain name, e.g. 
dc=[domainname],dc=de .

2) does your dnpass contain "funny" characters?

BTW: You do not habe no pass_filter or I deleted it last time.
