Applications can not find LDAP entries

[Martin <maillmgr@my01.net>]

Hello,

my apllicatons (i.e. postfix oder amavis-new) does not find any LDAP 
entry, when I use ldapsearch it is no Problem. I'm search for a few 
day's all about the web, docs, maillists and have no more Idear how to 
debug it.

I'm OpenLDAP 2.1.22

can anybody give me a hint how to solve this problem?

regards
Martin

# postmap -q "sysadmin@sample.de" ldap:/etc/postfix/ldap-test.cf

/etc/postfix/ldap-test.cf
server_host = hostname
