GYB Notes
WIKI: https://github.com/jay0lee/got-your-back/wiki 
GYB (Got Your Back) Lives on gadmin.emerson.edu. You RDP to this server. It is set up to use both http://elab.emerson.edu and emerson.edu service accounts
Directory: c:\gyb
Service account creds: c:\gyb\login creds
How to use serivce account: First you copy "oauth2service.json" file from C:\GYB\LOGIN CREDS and copy it to C:\GYB, overwriting the current json file in the directory. Make sure you use the --service-account flags
Service Account Syntax: c:\gyb\gyb.exe --email  <users email address> --service-account
If --service-account is omittied it will attempt to use teh credentials of the user specified in --email. This will open up a browser authorization session.
How to restore emails:  gyb --email youremail@gmail.com --action restore --local-folder "c:\my_gmail_backup" --label-restored "Old email"
you can append --service-account in order to restore the email to http://emerson.edu . Remember to copy the proper json file.

  3. Delete lastPassID from the user in AD
  4. Restart Service "Microsoft Active Directory Federated Services" on K2ADFS
  5. Start service ADSERVICE on K2ADFS

How to manage the spf record for emerson.edu
Emerson.edu uses a non-standard spf record because we use an excessive amount of email services.  We use a combination of a fake spf (fakespf.emerson.edu) that holds the text records of the authorized email services and a semi-flattened spf record that is used as our real spf record.
The official spf record is tracked in an excel spreadsheet 
https://emerson.box.com/s/6225cr3j9mq5jb3sswidjuecsb0dqtbp 
To add a record to our spf. 
  1. log into micetro and go into DNS > Emerson.edu
  2. search for “fakespf” 
  3. Open the excel document “Emerson’s SPF Record List.xlsx - Link is above
  4. Click on the “List of Approved Senders” tab
  5. add the same of the service and the spf record entry to the last line, remove if its needed
  6. Click on the “Master - fakespf record”
  7. add the include, ip4 or ip6 statement to the end of the record, before the “-all”
  8. Copy the contents of “Master - fakespf record” to “Old Master - fakespf record”
  9. In micetro, go into DNS > Emerson.edu
  10. Search for spf and then copy the records to the “Old Official SPF record” tab in the excel spreadsheet
    1. Please use notepad to help remove micetro formatting before adding it to the spreadsheet

  13. Enter “fakespf.emerson.edu” into the search field and click “survey domain”
  14. you will see an error that says “THERE IS SOMETHING WRONG WITH YOUR DOMAIN” you can ignore it, what we need is below that.
  15. Scroll down the listing of spf and ips till you see the section called “Record Flattening” 
  16. Copy the contents from fakespf.emerson.edu to spf#.fakespf.emerson.edu, and paste into the spreadsheet listed above, in the Official SPF Record,
    1. You MUST keep the include statement part of the 1st spf record for emerson.edu. Just add that to the end of the spf record
      

      exists:%{i}._spf.mta.salesforce.com include:spf1.emerson.edu -all
