This doc is self-contradictory because it suggests "to setup a technical user" when we "don't want to configure a technical user", and it doesn't give any solution when we are not the admin of the directory.
Here we learn that Tomcat JNDI Realm only works in "Administrator Login Mode" with an administrator login/password (in fact the "technical user" discussed above) : http://tomcat.apache.org/tomcat-7.0-doc/funcspecs/fs-jndi-realm.html >From this, it seems that roleSearchAsUser is only usefull when the anonymous >bind is allowed. It's another contradiction here, because it seems logical to >use this parameter especially when anonymous is not allowed. ________________________________________ De : Felix Schumacher [felix.schumac...@internetallee.de] Envoyé : jeudi 14 mars 2013 12:03 À : Tomcat Users List Objet : Re: JNDI property roleSearchAsUser not working as expected Am 13.03.2013 21:46, schrieb Eugène Adell: > Hello > > I am running the following : > java version "1.6.0_25" > Java(TM) SE Runtime Environment (build 1.6.0_25-b06) > Java HotSpot(TM) Client VM (build 20.0-b11, mixed mode, sharing) > Tomcat 7.0.37 > CentOS release 6.3 > > with this REALM configuration in server.xml : > <Realm > className="org.apache.catalina.realm.JNDIRealm" > connectionURL="ldap://***.***.***.***:389"; > > userPattern="cn={0},ou=users,dc=example,dc=com" > roleBase="ou=groups,dc=example,dc=com" > roleSubtree="true" > roleNested="true" > roleName="cn" > roleSearchAsUser="true" > roleSearch="(uniqueMember={0})" /> > > and this triggers this error during the startup : > Mar 13, 2013 8:14:49 PM org.apache.catalina.realm.JNDIRealm open > WARNING: Exception performing authentication > javax.naming.AuthenticationNotSupportedException: [LDAP: error code > 48 - anonymous bind disallowed] > at com.sun.jndi.ldap.LdapCtx.mapErrorCode(LdapCtx.java:3032) > at > com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2987) > at > com.sun.jndi.ldap.LdapCtx.processReturnCode(LdapCtx.java:2789) > at com.sun.jndi.ldap.LdapCtx.connect(LdapCtx.java:2703) > at com.sun.jndi.ldap.LdapCtx.<init>(LdapCtx.java:293) > at > com.sun.jndi.ldap.LdapCtxFactory.getUsingURL(LdapCtxFactory.java:175) > at > com.sun.jndi.ldap.LdapCtxFactory.getUsingURLs(LdapCtxFactory.java:193) > at > com.sun.jndi.ldap.LdapCtxFactory.getLdapCtxInstance(LdapCtxFactory.java:136) > at > com.sun.jndi.ldap.LdapCtxFactory.getInitialContext(LdapCtxFactory.java:66) > at > javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:667) > at > javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288) > at javax.naming.InitialContext.init(InitialContext.java:223) > at javax.naming.InitialContext.<init>(InitialContext.java:197) > at > javax.naming.directory.InitialDirContext.<init>(InitialDirContext.java:82) > at > org.apache.catalina.realm.JNDIRealm.open(JNDIRealm.java:2150) > at > org.apache.catalina.realm.JNDIRealm.startInternal(JNDIRealm.java:2241) ... > ... 27 more > Mar 13, 2013 8:14:49 PM org.apache.catalina.startup.Catalina start > INFO: Server startup in 34 ms > > > From what I understand, roleSearchAsUser property was designed for > people who need to bind on any LDAP where anonymous bind is not > authorized.

I read the docs as follows: If your directory server does not allow to scan for roles as anonymous user and you don't want to configure a technical user (by specifying connectionName and connectionPassword) you can delegate the credentials of the user that is currently logging in. It is not intended to set the user credentials for all ldap operations. The easiest way to fix it, is to setup an technical user inside your directory, which has no right other than to login and lookup your users, which would be the next operation.
