Setting directory while creating a new ldap entry throws exception

Creating a new entry in ldap creates the following exception:

Exception Message: No signature of method: groovy.util.ConfigObject.createEntry() is applicable for argument types: (org.springframework.ldap.core.DistinguishedName, javax.naming.directory.BasicAttributes) values: {uid=foo.bar, ou=Users, {objectClass=objectClass: fooAccount, cn=cn: foo}}
Caused by: groovy.lang.MissingMethodException: No signature of method: groovy.util.ConfigObject.createEntry() is applicable for argument types: (org.springframework.ldap.core.DistinguishedName, javax.naming.directory.BasicAttributes) values: {uid=foo.bar, ou=Users, {objectClass=objectClass: fooAccount, cn=cn: foo}}

I used the following config:

ldap {
directories {
fooDirectory {
url = "ldap://foo.de"
base = "o=foo,c=de"
userDn = "cn=manager,o=otop,c=de"
password = "mojo"
searchControls { timeLimit = 600 searchScope = "subtree" }
}
}
schemas = [ FooAccountLDAP, FooGroupLDAP ]

typemappings = [ de.foo.MyTypeMappings ]
}

As workaround omit setting the directory while setting attributes. then the default directory (if you only have one) is used and it works fine.

def newUser = new MySchemaClass()

// Assign the object a directory and a place in it.
//newUser.directory = "example" <-- coment this line
newUser.parent = "ou=people"
newUser.uid = "newuser"

// Set the attribute values
newUser.cn = "New"
newUser.sn = "User"

// Write to the directory
newUser.create()
