Creating an alias from a child entry to the ancestor causes an error (return
 code 36)
----------------------------------------------------------------------------

Key: DIRSERVER-803
URL: http://issues.apache.org/jira/browse/DIRSERVER-803
Project: Directory ApacheDS
Issue Type: Bug
Affects Versions: 1.0
Environment: * ApacheDS 1.0.0
* Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_07-b03)
* Windows XP Professional SP2

Reporter: Stefan Zoerner
Priority: Minor


It fails to import the following two entries into ApacheDS 1.0 (default serv
er.xml).
The second entry is an alias to the first one, and is directly located below
 the first entry:

dn: ou=Singers,dc=example,dc=com
ou: Singers
objectclass: top
objectclass: organizationalUnit

dn:  ou=Songwriters,ou=Singers,dc=example,dc=
com
ou: Songwriters
objectclass: top
objectclass: organizationalUnit
objectclass: alias
aliasedobjectname: ou=Singers,dc=example,dc=com

Here is the result I got from an ldapmodify attempt:

$ ldapmodify -h localhost -p 10389 -D "uid=admin,ou=system" -w ****** -q -c 
-a -f aliasSingers.ldif
ldap_add: Unknown error
ldap_add: additional info: failed to add entry ou=Songwriters,ou=Singers,dc=
example,dc=com: [36] aliasDereferencingProblem - attempt to create alias
 with cycle to relative ou=Singers,dc=example,dc=com not allowed from descen
dent alias 2.5.4.11=songwriters
,2.5.4.11=singers,0.9.2342.19200300.100.1.25=example,0.9.2342.19200300.100.1
.25=com

It seems that ApacheDS does not allow to create an alias from a descendant. 
I tried the same with Tivoli Directory Server 6.0 and Sun Java System Direct
ory Server 5.2, both allowed this constellation.

Find attached a JNDI JUnit test which is able to cause the error by adding t
wo entries programmatically.
