LDAP Group Authorization

Categories: Authorization Plugin
Author: Adrian Png

This is a rewrite of the original plugin and now no longer uses the DBMS_LDAP and DBMS_LDAP_UTL packages for performing LDAP lookups. Instead, the plugin uses the APEX_LDAP API for interacting with the LDAP server. Hence, only a network ACL privilege is needed for the APEX_05000 schema to communicate with the LDAP server.
 
Documentation to follow, but it is pretty self-explanatory. However, please feel free to contact me on Twitter (fuzziebrain) if you do need help or have any questions regarding the plugin. 
 
Last but not least, this is very much work in progress. If you would like to contribute or enhance the plugin, please feel free to fork the project on Github.
 
Tested to work with:
- Novell eDirectory
- Microsoft Active Directory

Correct. I needed to do a

DBMS_NETWORK_ACL_ADMIN.ADD_PRIVILEGE

for the existing ACL, addressing the parsing schema user.

Somewhat confusing: for the LDAP authorization to work correctly, it is sufficient to have principal APEX_040100. Now I see, that for each application schema that implements network operations, this setting has do be done, too.

Hi Tom,

Thanks for your feedback.

Did you also include the parsing schema in the ACL? This plugin uses the DBMS_LDAP and DBMS_LDAP_UTL package and runs as the parsing schema.

Best regards,
Adrian

getting ORA-24247 - though ACL is define

Adrian,

this is a fine plug-in I believe. I have an issue though.

While I successfully run authentication to our OpenLDAP server, you
plugin will evoke an ORA-24247:

is_internal_error: true
apex_error_code: WWV_FLOW_PLUGIN_ENGINE.RUN_PLSQL_ERR
ora_sqlcode: -24247
ora_sqlerrm: ORA-24247: Netzwerkzugriff von Access Control-Liste (ACL) abgelehnt
component.type: APEX_APPLICATION_AUTHORIZATION
component.id: 107858606744715259
component.name: memberof_edv
error_backtrace:

ORA-06512: in "SYS.DBMS_LDAP_API_FFI", Zeile 25
ORA-06512: in "SYS.DBMS_LDAP", Zeile 48
ORA-06512: in Zeile 35
ORA-06512: in Zeile 68
ORA-06512: in "SYS.DBMS_SYS_SQL", Zeile 1926

ORA-06512: in "APEX_040100.WWV_FLOW_PLUGIN_ENGINE", Zeile 983

This is quite a riddle, because I can successfully run the following
as APEX_040100:

SQL> alter session set current_schema=APEX_040100;

Session altered.

SQL> set serveroutput on
SQL> l

7 l_dummy := dbms_ldap.simple_bind_s(l_session, 'uid=auser,ou=people,dc=domain,dc=ctry', '123456');
8 dbms_output.put_line('authenticated');
9 l_dummy := dbms_ldap.unbind_s(l_session);
10 exception when others then
11 l_dummy := dbms_ldap.unbind_s(l_session);
12 raise;
13* end;
SQL> /
