send email return error ORA-24250: No supported authentication scheme found

MaahjoorSep 25 2017

Dear all,

i am using Apex 5.1 on oracle 12c R1 with windows server 2012.

i am trying to send email from apex application. i did the following;

Install utl_mail/utl_smtp

cd $ORACLE_HOME/rdbms/admin

sqlplus / as sysdba

SQL> @utlmail

SQL> @utlsmtp

SQL> @prvtmail.plb

SQL> GRANT EXECUTE ON utl_mail TO PUBLIC;

SQL> GRANT EXECUTE ON utl_smtp TO PUBLIC;

SQL> alter system set smtp_out_server='mail.hct.edu.om' scope=both;

ACL: Access Control List

Create ACL

begin

dbms_network_acl_admin.create_acl (

acl => 'utl_mail.xml',

description => 'Allow mail to be send',

principal => 'STD',

is_grant => TRUE,

privilege => 'connect'

);

commit;

end;

Add Privilege

begin

dbms_network_acl_admin.add_privilege (

acl => 'utl_mail.xml',

principal => 'STD',

is_grant => TRUE,

privilege => 'resolve'

);

commit;

end;

Assign ACL

begin

dbms_network_acl_admin.assign_acl(

acl => 'utl_mail.xml',

host => 'mail.hct.edu.om' );

commit;

end;

Apex Code

i create a button with dynamic action and add the following pl/sql code

BEGIN

apex_mail.send( p_to => 'Muhammad.idrees@hct.edu.om',

p_from => 'Muhammad.idrees@hct.edu.om',

p_body => 'The Body of Email',p_subj => 'My Plain text message');

END;

my instance settings are below

when i run the page, it never send me the email.

then i issue the following query

SELECT * FROM APEX_MAIL_QUEUE;

ORA-24250: No supported authentication scheme found

please note that i was able to send the email from the sqlplus using the following procedure

begin

utl_mail.send(

sender => 'Muhammad.idrees@hct.edu.om',

recipients => 'Muhammad.idrees@hct.edu.om',

message => 'My first email'

);

end;

it seems that my apex is not properly configured. i am using LDAP authentication.

any clue how to fix it?

thank you.
