java and ldap

[Bjoern Eberth]

Hi there,

i have a few problems accessing a ldap server with the java api JNDI.
I am able to get attributes with the following code:

env.put(Context .INITIAL_CONTEX T_FACTORY,"com. sun.jndi.ldap.L dapCtxFact
ory");
env.put(Context .PROVIDER_URL, "ldap://server:10389/");
env.put(Context .SECURITY_AUTHE NTICATION, "simple");
env.put(Context .SECURITY_PRINC IPAL, "user=benut zer, ou=irgendwas,
o=nochwas, c=de");
env.put(Context .SECURITY_CREDE NTIALS, "passwort") ;
try {

// Create the initial directory context
DirContext ctx = new InitialDirConte xt(env);
// Ask for all attributes of the object
Attributes attrs =
ctx.getAttribut es("apc=einAPC, ou=irgendwas,o= nochwas,c=de");
// Find the ip adress and print
System.out.prin tln("ip: " + attrs.get("IP") .get());
} catch (NamingExceptio n e) {
System.err.prin tln("Problem getting attribute:" + e);
}

But what to do, if i don't know the name of the APC?
I tried with searching, but i don't get any results:

try {
SearchControls ctls = new SearchControls( );
ctls.setSearchS cope(20);
// Specify the search filter to match
String filter = "(apc=*)";
DirContext ctx = new InitialDirConte xt(env);
// Search for objects using the filter
NamingEnumerati on answer = ctx.search("", filter, ctls);
System.out.prin tln("sind antworten
vorhanden?"+ans wer.hasMore()+" ");
while (answer.hasMore ()) {
SearchResult sr = (SearchResult)a nswer.next();
System.out.prin tln(">>>" + sr.getName());
printAttrs(sr.g etAttributes()) ;
}
} catch (Exception err) {
System.out.prin tln("fehler: " + err);
}

Structure of the directory:
c=de
|- o=nochwas, c=de
|-ou=irgendwas, o=nochwas, c=de
|-ou=irgendwas,
o=nochwas, c=de, apc=someAPC
ou=irgendwas,
o=nochwas, c=de, apc=anotherAPC

All apc's have an attribute apc.

Where is the problem?

Thx in advance
