rewriting (invalid) bindDN ?
Hi list,
I've just set up a ldap proxy on witch I wish users may bind with their cn
instead of dn.
Some reading let me say it's possible
- slapo-rwm (5)
- http://blogs.turmzimmer.net/2008/06/26#ldap-3
- http://www.openldap.org/lists/openldap-software/201004/msg00065.html
and some more
I run slapd 2.4.11 from Debian Lenny. Here is slapd.conf :

When trying to bind from Thunderbird as client with just "MyCN", connection fail
with "invalid dn". I expected some info about rwm rewriting
syslog> slapd[11027]: conn=5 op=0 do_bind
syslog> slapd[11027]: >>> dnPrettyNormal: <MyCN>
syslog> slapd[11027]: conn=5 op=0 do_bind: invalid dn (glachenal)
syslog> slapd[11027]: send_ldap_result: conn=5 op=0 p=3
syslog> slapd[11027]: send_ldap_result: err=34 matched="" text="invalid DN"
syslog> slapd[11027]: send_ldap_response: msgid=1 tag=97 err=34
syslog> slapd[11027]: conn=5 op=0 RESULT tag=97 err=34 text=invalid DN
When trying to bind with a valid DN, rwm works as expected. (And of course bind
failed because of unexistent rewritten DN)
syslog> slapd[11135]: >>> dnPrettyNormal: <cn=MyCN,ou=SubOU,ou=OU,o=MyO>
syslog> slapd[11135]: <<< dnPrettyNormal: <cn=MyCN,ou=SubOU,ou=OU,o=MyO>, <cn=MyCN,ou=SubOU,ou=OU,o=MyO>
syslog> slapd[11135]: conn=1 op=0 BIND dn="cn=MyCN,ou=SubOU,ou=OU,o=MyO" method=128
syslog> slapd[11135]: do_bind: version=3 dn="cn=MyCN,ou=SubOU,ou=OU,o=MyO" method=128
syslog> slapd[11135]: [rw] bindDN: "cn=MyCN,ou=SubOU,ou=OU,o=MyO" -> "cn=cn=MyCN,ou=SubOU,ou=OU,o=MyO,ou=SubOU,ou=OU,o=MyO"
syslog> slapd[11135]: >>> dnPrettyNormal: <cn=cn=MyCN,ou=SubOU,ou=OU,o=MyO,ou=SubOU,ou=OU,o=MyO>
syslog> slapd[11135]: <<< dnPrettyNormal: <cn=cn\3DMyCN,ou=SubOU,ou=OU,o=MyO,ou=SubOU,ou=OU,o=MyO>, <cn=cn\3DMyCN,ou=SubOU,ou=OU,o=MyO,ou=SubOU,ou=OU,o=MyO>
So, why isn't rwm not used when supplying an invalid dn ?
