Fixing TXTRDATATooLong Errors for AWS Route 53

RFC 4408 3.1.3 says

....
     IN TXT "v=spf1 .... first" "second string..."
 
   MUST be treated as equivalent to
 
      IN TXT "v=spf1 .... firstsecond string..."
 
   SPF or TXT records containing multiple strings are useful in
   constructing records that would exceed the 255-byte maximum length of
   a string within a single TXT or SPF RR record.

so if you are getting error “TXTRDATATooLong” a solution for you will be splitting it into multiple strings within the same record set. For example, instead of:

"v=DKIM1; k=rsa; g=*; s=email; h=sha1; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCTMZcHm9p2CwCgFx3
reSF+ZmoaOvvgVL5TKTzYZK7jRktQxPdTvk3/yj71NQqBGatLQIDAQAB;"

you can pick a split point where each part is less than 255 characters long and put [double quote][space][double quote]

for example I tried:

"v=DKIM1; k=rsa; g=*; s=email; h=sha1; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCT" "MZcHm9p2CwCgFx3reSF+ZmoaOvvgVL5TKTzYZK7jRktQxPdTvk3/yj71NQqBGatLQIDAQAB;"

and as a result I’ve got:

dig -t TXT long.xxxxxx.yyyy @ns-iiii.awsdns-jj.org.
;; ANSWER SECTION:
long.xxxxxxx.yyyy. 300    IN      TXT     "v=DKIM1\; k=rsa\; g=*\; s=email\; h=sha1\; t=s\; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDx2zIlneFcE2skbzXjq5GudbHNntCGNN9A2RZGC/trRpTXzT/+oymxCytrEsmrwtvKdbTnkkWOxSEUcwU2cffGeaMxgZpONCu+qf5prxZCT" "MZcHm9p2CwCgFx3reSF+ZmoaOvvgVL5TKTzYZK7jRktQxPdTvk3/yj71NQqBGatLQIDAQAB\;"

Note that returned TXT contains [double quote][space][double quote] , however the RFC above mandates that string to be treated as the same as concatenated one.

Note that your example does the same too on 128 character boundary

dig s2048._domainkey.yahoo.com TXT                                                                                                                                      /workspace/stepany-HaasControlAPI-development

Limit Elasticsearch Memory Use (Heap Size)

Add the following to /etc/elasticsearch/jvm.options.d/custom.options:

-Xms2g
-Xmx2g

According to official documentation you should avoid adding custom options directly in jvm.options.

Receive a User’s UPN, Email, First and Last Name via Azure Active Directory Custom Manifest

In May 2019 Microsoft has made the new and improved App Registration portal generally available. For some time this new portal has been available under the Azure Active Directory > App registration (preview) menu in the Azure Portal. The old App Registration is still available under Azure Active Directory > App registration (legacy) but most likely it will be discontinued soon.

The ID token does no longer by default contains fields such as user principal name (UPN), email, first and last name, most likely to ensure that personal data is handled with more consideration. As a result, you must manually update the app registration’s manifest to ensure that ID tokens include the UPN, email, first and last name by adding these optional claims.

Go to Azure Portal > Azure Active Directory > App registrations
Find your application registration (you may click on the All applications tab)
Click Manifest
Update the Manifest and change the optionalClaims node as shown below

"optionalClaims": {
	"idToken": [{
			"name": "family_name",
			"source": null,
			"essential": false,
			"additionalProperties": []
		}, {
			"name": "given_name",
			"source": null,
			"essential": false,
			"additionalProperties": []
		}, {
			"name": "upn",
			"source": null,
			"essential": false,
			"additionalProperties": []
		}, {
