Email authentication fail

We have 2 email sub-accounts to our VOL account. We access these via separate instances of Eudora, as separate 'users' under Windows. Per the latest VZ notification, I changed the email settings for both users, to 'pop.verizon.net', 'smtp.verizon.net', and (SSL) 'required, alt port'. When I went to get email, I had to re-enter the password. (I used the 'master account' password.)
On one sub-account, this worked fine.
On the other, we get an "authentication failed" error. Any thoughts would be appreciated. In particular, can a sub-account have a different password than the root account? (My records don't show that we did that, but things can be forgotten.)
Thanks,
George

There is no relationship among passwords for either the primary account or any of the nine allowed subaccounts. In many cases it is useful to have the same passwords, of course, but there is no requirement to do so.

Email authentication fails consistently

I use the built in email client to access my AOL accounts (2). Each has a different password. The password has not changed and I can successfully log in to AOL and access both accounts. Almost on a daily basis I receive a login failed, could not be authenticated on one email acct or the other (sometimes both). If I re-enter the "unchanged" password, it connects and I get my mail. More recently, this happens way too often.
Any thoughts.

Did you setup those accounts under the AOL option? Try removing them and adding again under the "Other" email account option. This way you can manually enter and verify the email server settings for the accounts.

TS4002 Can you tell me if the smtp settings have changed recently? I use me/ICloud mail with Outlook and can not receive emails but outgoing emails are no longer working. Error message is: Authentication failed because Outlook doesn't support any of the

I am able to receive messages on my IMac using Outlook but am unable to send. I've had no trouble in the past but began receiving the following messages today.

I am able to send messages using this account on my IPhone and IPad so the IMac is the only place I am having issues. Any advice?

Here are the correct settings. They have never changed since iCloud debuted a year ago.
Server information
IMAP (Incoming Mail Server) information:
Server name: imap.mail.me.com
SSL Required: Yes
Port: 993
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
SMTP (outgoing mail server) information:
Server name: smtp.mail.me.com
SSL Required: Yes
Port: 587
SMTP Authentication Required: Yes
Username: [email protected] (use your @me.com address from your iCloud account)
Password: Your iCloud password
Note: If you receive errors using SSL, try using TLS instead. SSL is required for both IMAP and SMTP connection with iCloud. POP is not supported by iCloud.

Cannot access my email, Sending of password did not succeed. Authentication failed.

Was able to use my Thunderbird Mozilla email on both computers and then suddenly on both I rc'd msg that, "Sending of password did not succeed. Mail server incoming Verizon.net responded Authentication Failed".
On the computer that I use all the time, I played around with it and all of a sudden it was "fixed". No idea what I did.
Today I turned on the other computer that is only used by the Grandkids for games, etc., and received the same msg and decided it was time to fix but am not able to figure out how.

Best starting point is to remove all stored passwords for the affected accounts.

Use the filter at the top to locate all entries relating to the affected account.

ColdFusionMX7 Email - Error "Authentication Failed"

We are running Exchange 2007 and I am trying to setup the email portion of ColdFusion. Under the admin tool "Mail" settings I am setting my account up as:
user:pass@smtpserverip
I have alos tried:
domain\user:pass@smtpserverip
I can smtp to my mail server from that server with no issues. The mail log gives an error:
"Error","scheduler-2","11/20/09", "12:58:18",,"Authentication Failed"

Suppose my username at the mail server is 01BKBK02. The mail server is mail.bkbkInc.com, internal IP 193.68.95.122, public IP 95.96.46.152
Then these login names are possible:
[email protected]
[email protected]
[email protected]
However, the second one is only possible if the mail server is within your private network.

Authentication failed

hello!
my aol email has frozen on my phone. I tried refreshing and that did not work. I deleted my email account and now when I try to restart the email account it says authentication failed (after checking incoming server settings). my friend has the same phone, her email froze last week, she refreshed it and now it works. I don't understand why mine is not working. any help or suggestions would be appreciated.

Artesianrev,
We want you to be able to enjoy using your email account on your Samsung Galaxy S4! Have you checked to make sure your email account does not have 2-step verification set up on it? http://bit.ly/1njb5e4 Are you manually entering it the server information for the email account? http://vz.to/1jZGAq6

Authentication failed Entourage doesn't support available authentication...

I tried to set up and exchange account through Entourage. It works fine for receiving, but I cannot send through the account, I assume because I do not have a Certificated Authorization. So I tried to create a Certificate, since the help and instructions suggested such. This meant I had to create on in my Keychain.
Well nothing worked, so I decided I would cheat and just create an account to send from Entourage using my exchange email account as an alias. The down side being exchange would not capture the "Sent" messages. Oh Well, I could live with that.
This is when I started getting this error and Entourage would not send the message:
"Authentication failed because Entourage doesn't support any of the available authentication methods."
I eventually learned to go to the Keychain and try to verify the error and repair it. The error that appears on verification is:
"Item “mail.bellsouth.net” has unspecified value for port attribute"
Once the repair is executed, it shows it is repaired, but Entourage will still not send mail. So,...yes there is more...I decided to create an identical account to my working bellsouth account, that still works perfectly by the way, and the new account demonstrates the same problem and will not send, but all settlings are identical to my original POP3/SMTP account.
Help! I do not have time machine running, but that is another issues, so lets see if I can fix this first.
Thanks for whoever can come to the rescue!
BarryCuda

I believe this is a KeyChain issue, not an Entourage issue, but it is hard to tell. Can you tell? The reason I believe this is because I now cannot create an duplicate Account and have the KeyChain work properly with Entourage.
I will post there as well, but please provide some guidance if you can. Where would I post KeyChain issue? I couldn't quite find a germane Forum.
Sorry if I posted in the wrong place, but I have to start somewhere since it is not clear where the problem lies.
Thanks,
BarryCuda

Authentication Failed - Control or Observe

First things first... this is what I have:
ARD Admin: 17" MacBook Pro running 10.5.1 and ARD 3.2
Want to control: Mirror Door PowerMac G4 with 10.4.11 and ARD client version 3.2.1
I had the same problem prior to updates and upgrading my OS to 10.5. I can manage this computer, and share my screen with it. But I cannot observe or control it. When I try this, I receive Authentication Failed.
I have tried re-installing the client via kickstart on the client machine. I have uninstalled all privs and settings via kickstart. I have also reset all these settings and restarted the menu, console, and agent.
On my MBP I have removed the computer and re-added it many times. I have checked all settings on the client... flushed dns cache... fixed any network problems... verified that firewall is not turned on. I even cleaned all caches and ran maintenance on it.
All of this I have done, and I keep receiving the same error message. Does anyone have any other ideas... I guess I could re-install the system, but I'd rather not have to do that.
Thanks,
Ken

I lost access to two of my clients as well. Could see them in scanner and they even showed up as available, light blue, but I could not control or observe. So the following fixed the problem for me.
Open terminal:
ssh shortusername@ipaddress for specific client
rm -rf /var/db/RemoteManagement
rm /Library/Preferences/com.apple.RemoteDesktop.plist
rm ~/Library/Preferences/com.apple.RemoteDesktop.plist
rm -r /Library/Application\ Support/Apple/Remote\ Desktop/
rm -r ~/Library/Application\ Support/Remote\ Desktop/
Then create special ARD client install package with ARD admin app with all the settings configured. I don’t know how to install and run the package via ssh so I just emailed it to the client and had them open the package and run the install.
It worked for me, I now have access to the clients that I lost access to (verify failed)

Hi .
I tried your code , and I got the same exeption ..
But when I changed a little bit in it , it worked ... :
Properties props = new Properties();
props.put("mail.smtp.host","host");
props.put("mail.smtp.port","25");
props.put("mail.smtp.auth","true");
Session session = Session.getInstance(props,null);
session.setDebug(true);
Message msg = new MimeMessage(session);
msg.setSentDate(new Date());
msg.setFrom(new InternetAddress("[email protected]"));
InternetAddress[] addTo = new InternetAddress[1];
for(int i=0; i<addTo.length; i++)
addTo[i] = new InternetAddress("[email protected]");
msg.setRecipients(Message.RecipientType.TO, addTo);
msg.setSubject("HIIIIIIIIIIIII");
msg.setText("HIIIIIIIIIIII");
Transport tr = session.getTransport("smtp");
tr.connect("[email protected]","xxxx");
tr.sendMessage(msg,msg.getAllRecipients());
Actually I used : tr.sendMessage(msg,msg.getAllRecipients());
instead of : tr.send(msg) and it worked for me ..
Plase try it and let me know ..

Authentication failed in Content Viewer

I have a client who can’t log into Content View with his Adobe I.D., thus he cannot see the project I’m developing for him. When logging in he gets the dreaded “Authentication Failed” message. He has used Content Viewer in the past with no problem, can log into Adobe.com, is connected to the Internet and his account is verified. I even changed his account email address so it would re-verify but to no avail. I know this topic has been discussed here with varing results, but nothing has resolved the issue. I’ve tried his account information on my iPad with the same results, but my account works fine. I chatted online and by phone with tech support, but that was absolutely worthless. He hasn’t tried making a new account, but that really isn't acceptable and doesn't bode a lot of confidence in the product. Thank you.
Bil

There is a known issue that's impacting some customers. Can you send me a private message with the Adobe ID of the person having this trouble and I'll have someone from product support investigate and resolve the issue (there's steps they can do that I can't to resolve this)

They already changed the password for service accounts running using that admin account with new password. There is no issues in domain other than this, users can login and services are fine. However, account lockout policy is disabled and if it is enabled
I think they will have a huge issue due to this Kerberos authentication failure.
Please help!

Hi,
Did you confirm the time sync issue?
The error code 0x25, means Workstation’s clock too far out of sync with the DC’s , so i suggest you could check the time snyc of the computer failing pre-auth with DC firstly.
