I'm running an APEX 24.1 application on Oracle Linux 7.9 with Oracle DB 21c XE. The application uses LDAP_BASIC authentication, but login attempts are unsuccessful. The debug log shows the following error:
Exception in "LDAP_BASIC":
Error Stack: ORA-24247: Network access denied by Access Control List (ACL)
ORA-06512: at "SYS.DBMS_LDAP_API_FFI", line 25
ORA-06512: at "SYS.DBMS_LDAP", line 48
Backtrace: ORA-06512: at "SYS.DBMS_LDAP_API_FFI", line 25
ORA-06512: at "SYS.DBMS_LDAP", line 48
ORA-06512: at "APEX_240100.WWV_FLOW_CUSTOM_AUTH_LDAP", line 70
I've already added several users to the ACL, including APEX_PUBLIC_USER, APEX_240100, ANONYMOUS, and ORDS_PUBLIC_USER, but the error persists.
I'm not sure how to proceed with debugging this issue.
Any guidance or suggestions would be greatly appreciated.
