i'm using Grails 2.5.1 and mail:1.0.7 plugin to send emails , but when i'm using it i always getting the bellow error :
Class:javax.mail.AuthenticationFailedExceptionMessage:535-5.7.8 Username and Password not accepted. Learn more at 535 5.7.8 https://support.google.com/mail/answer/14257 qq4sm4579366wjc.14 - gsmtp
although i can login with the provided credentials successfully from the browser !!
here are my configurations in the Config file :
grails {
mail {
host = "smtp.gmail.com"
port =465
username = "****"
password = "***"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
and here is the action :
mailService.sendMail{
to userInstance.toEmail
subject userInstance.subject
html "<strong>Test</strong> "
}
anything i'm missing ?
It may be because of gmail's security feature for less secure apps to get authenticated. Just turn on the access for less secure apps.
Follow below steps:
1 Login to your gmail account
2 Access the url:
https://www.google.com/settings/security/lesssecureapps
3 Select "Turn on"
If you have gmail - settings for plugin are correct (i have the same and they are working) , but if your email is not gmail you must have other config.
By the way if you gmail :
Username and Password not accepted.
your username or password is wrong, try to login with this Username and password, watch out for register of letters.

I created a new connected app in salesforce
I am trying to authenticate using username and password - OAuth method to fetch a token using Postman
I am hitting the following endpoint https://login.salesforce.com/services/oauth2/token with my client_id, client_secret, username and password
I am getting the following error:
{
"error": "invalid_grant",
"error_description": "authentication failure"
}
The username and password are verified to be correct independently
What am I missing here?
If you are using Username and Password OAuth authentication, please make sure you have concatenated the unique security key (for the username that you are using) with the password. For instance (example in Python), your request should be:
import requests
import json
params = {
"grant_type": "password",
"client_id": "client_id", # Consumer Key
"client_secret": "client_secret", # Consumer Secret
"username": "username", # The email you use to login
"password": "password + unique_security_key"}
headers = {'content_type':'application/x-www-form-urlencoded'}
r = requests.post("https://login.salesforce.com/services/oauth2/token", params=params, headers=headers)
access_token = r.json().get("access_token")
instance_url = r.json().get("instance_url")
print("Access Token:", access_token)
print("Instance URL", instance_url)
To get the security key:
Login to your Salesforce Account
Click on your username on the top right-hand side.
On the left-hand side pane, click on Personal > Reset My Security Token
A Unique security token will be sent to your email. Please concatenate the key with your password.
If you still experiencing the error, please check the following steps:
Navigate Apps > Manage Connected Apps > Your Connected App > Edit > OAuth Policies > Enable Permitted users to All users may self-authorize
AND
Manage Apps > Connected Apps > Your Connected App > Enable IP Relaxation to Relax IP restrictions.
Hope this helps.
I am building a form in C#, .NET, and MVC. On the back end the form will send its contents over email. For testing, I am using a local install of hMailServer.
Initially I set HMS to run as localhost.localdomain; the SMTP setting for "local host name" is localhost. I attempted to connect to it on port 587, like so:
SmtpClient smtp = new SmtpClient
{
Host = WebConfigurationManager.AppSettings["emailServer"],
Port = 587,
EnableSsl = true,
DeliveryMethod = SmtpDeliveryMethod.Network,
UseDefaultCredentials = true,
Credentials = networkCredential
};
I have double- and triple-checked that the credentials are the mail server user and password that I set. Here they are, in case this helps:
<add key="emailUser" value="user#localhost.localdomain"/>
<add key="emailPassword" value="~~~"/>
<add key="emailServer" value="localhost.localdomain"/>
When using localhost.localdomain, sending mail throws an exception, with the outer message: "Failure sending mail", and the inner message: "The remote name could not be resolved: 'localhost.localdomain'."
So I tried using companyname.com. Sending mail throws an exception, with the outer message: "Failure sending mail", and the inner message: "Unable to connect to the remote server."
I expect either my HMS domain config is wrong or my protocol config is wrong. The HMS documentation didn't help me, but I may not have known what to look for.
ETA
hMail server status shows zero processed messages in a week, despite all my testing.
Here is how I configured it for development:
Created host file entry like following:
local.myname.com 127.0.0.1
Once done, I opened command prompt and make sure it is updated. I tested it by following:
tracert local.myname.com
It should return 127.0.0.1 if host file entry is updated.
Next, in hmail, we need to create a new domain: local.myname.com and add an email address with password. so your email address would be something like admin#local.myname.com.
Next is, in advance you need to double check the protocols configuration and IP range vs authentication configuration as well.
In my case I configured to block external incoming and outgoing emails and skipped authentication for internal emails. So basically that;s what you can do in advance - IP range configuration. Then with the development, you just need to make sure all your emails are *#local.myname.com and it should work.
Also enable logging in hmail to get detailed error that can help solve the problem because hmail's help documentation works directly with their error codes nicely.
hMail is actually good choice for real emails. For development, I would recommend using smtp4dev though.

I have setup a CAS server up and running at port: 8443 url -> https://ekansh/cas.
I can see the login page and i am successfully able to login using mysql database user table credentials. and even logout and see status.
I created a demo grails app, installed spring security plugin and created user role mappings by s2-quickstart. and scaffolding domains.
I added the
compile ":spring-security-core:2.0-RC4"
compile ":spring-security-cas:2.0-RC1"
dependencies.
Added configurations in Config.grovy
grails.plugin.springsecurity.cas.active = true
grails.plugin.springsecurity.cas.loginUri = '/login'
grails.plugin.springsecurity.cas.sendRenew = false
grails.plugin.springsecurity.cas.serviceUrl = 'http://ekansh:8095/app1/j_spring_cas_security_check'
grails.plugin.springsecurity.cas.serverUrlEncoding = 'UTF-8'
grails.plugin.springsecurity.cas.key = 'grails-spring-security-cas'
grails.plugin.springsecurity.cas.artifactParameter = 'ticket'
grails.plugin.springsecurity.cas.serviceParameter = 'service'
grails.plugin.springsecurity.cas.filterProcessesUrl = '/j_spring_cas_security_check'
grails.plugin.springsecurity.cas.proxyCallbackUrl = 'http://ekansh:8095/app1/secure/receptor'
grails.plugin.springsecurity.cas.useSingleSignout = true
grails.plugin.springsecurity.cas.serverUrlPrefix = 'https://ekansh:8443/cas'
grails.plugin.springsecurity.cas.proxyCallbackUrl = 'http://ekansh:8095/app1/secure/receptor'
grails.plugin.springsecurity.cas.proxyReceptorUrl = '/secure/receptor'
grails.plugin.springsecurity.logout.afterLogoutUrl ='https://ekansh:8443/cas/logout?url=http://ekansh:8095/app1/'
grails.plugin.springsecurity.providerNames = ['casAuthenticationProvider']
Nw when i run this app, i get redirected to cas server page, i enter the credentials, it logs me into cas server, but it sends me to the spring security login page with message that
Sorry, we were not able to find a user with that username and password. And i am not even able to sign in to the application from this point.
What am i missing ? Why am i getting spring security login page.
I also found that when i comment line grails.plugin.springsecurity.providerNames = ['casAuthenticationProvider'], i am able to login to the system. I have not altered the casAuthenticationProvider.
Any help would be appriciated.
I found the answer to my question after a lot of research. Basically i did mess up with the configurations of the cas server.
The user was getting logged into the cas server but a ticket was not being generated for the same user, thus it was still sending a user not authenticated response back to the application and spring security, was redirecting to the login page.
i am new to Grails.
i am using mail 1.0 pluguin..
i configured config file as below
grails {
mail {
host = "smtp.gmail.org"
port = 465
username = "myaccount#gmail.com"
password = "mypassword"
props = ["mail.smtp.auth":"true",
"mail.smtp.socketFactory.port":"465",
"mail.smtp.socketFactory.class":"javax.net.ssl.SSLSocketFactory",
"mail.smtp.socketFactory.fallback":"false"]
}
}
and used sendMail() in controller as below
sendMail {
to "myanotheraccount#gmail.com"
subject "New User Confirmation"
body "how are u"
}
I have no firewall issues.
but it show s error as Connection refused.......???
Probably a configuration issue, have you looked at this example which shows how to use Mailgun via SMTP: https://github.com/jbayer/mail-java
I am just learning grails and have a problem with an app that works fine when I run it in Netbeans but shows strange behavior when deployed to Tomcat 7.0.22 on a Centos 5.4 server. I am using the proxy_ajp to make the app available with apache.
The problem seems to be with the session not being maintained after a redirect so that I lose the login information causing the app to try to login again.
My proxy_ajp settings are
<Location /PreyerBooks >
ProxyPass ajp://localhost:8011/PreyerBooks
ProxyPassReverse ajp://localhost:8011/PreyerBooks
</Location>
the app is deploying without errors and the connectivity to the database and LDAP is working. I tested this by logging in the authenticate method as follows
UserController - authentication function
def authenticate = {
def password=passhash(params.password)
log.info " login attempt ${params.login} - ${params.password} - ${password}"
def match = User.findAll(
directory: "user",
filter: "(&(uid=${params.login})(userpassword=${password}))"
)
log.info " match ${match}"
if (match) {
def user = Employee.findByLogin(params.login)
log.info " user ${user} - ${user?.role}"
if(user){
session.user = user
log.info "success"
flash.message = "Hello ${user.firstname}!"
redirect(controller:"Book", action:"index")
}else{
log.error "failed login attempt mismatch to ldap ${params.login}"
flash.message = "Sorry, ${params.login}. Please try again."
redirect(action:"login")
}
}else{
log.error "failed login attempt ${params.login} - ${params.password}"
flash.message = "Sorry, ${params.login}. Please try again."
redirect(action:"login")
}
}
BookController - auth function (checks if logged in)
def beforeInterceptor = [action:this.&auth, except:[]]
def auth() {
log.info "BookController:auth() ${session}"
if(!session.user) {
redirect(controller:"User", action:"login")
return false
}
log.info "BookController:auth() working"
return true
}
The log shows
INFO books.UserController - login attempt username - password - passwordhash
INFO books.UserController - match [de.preyer.books.User#d4a1cc]
INFO books.UserController - user username - admin
INFO books.UserController - success
INFO books.BookController - BookController:auth() Session Content:
The session.user variable has vanished. I checked the passwordhash and it correctly matches against the LDAP server (hence the object reference in match). This user is correctly found in the database where it gains its role.
I cannot access the app directly avoiding the apache ajp as the port is blocked in the firewall and I cannot open it. Thus I cannot test if the problem is in the ajp or tomcat in general
I have tried searching for the criteria specified as the title but find nothing relevant.
a) browser cookies are enabled and working, I tried Safari, Firefox and Chrome without success. I do not think this is a browser issue as the same browsers work with the app in NetBeans (using jetty I think)
b) I have set grails.serverURL = "http://servername/PreyerBooks" to the fully qualified domain
If I turn of the auth the app works.
I must be doing something wrong or have missed a step in the deployment.
Now I know I can include a plugin using Spring Core but this is overkill for my application and adds a further level of complexity to the debugging. I wish to get the current implementation working before moving on. The logic is copied from the Grails 2.1.0 documentation so it should work.
I read in httpSession that things must be serializable but if the example in the documentation does not work why does the app work when I run it in NetBeans?
I am at a loss. Any help would be much appreciated.
Use the spring-security-core plugin (or Shiro, or any established, proven security implementation). It's not complex, and rolling your own security is a quick path to getting hacked.
