This part could be done in web ui - check for 
<SERVICENAME>/ipa1.stt.local@STT.LOCAL

where <SERVICENAME> is usually DNS, HTTP and ldap
----

The webui also shows a dogtag/ipa1.stt.local@STT.LOCAL but no other dogtag 
URL's (like the new master). Is it no longer needed or should it be changed to 
the new CA-master?

yes


If by ipa1_ETC you mean (assuming that your realm is STT.LOCAL):
> Dn: cn=ipa-http-delegation,cn=s4u2proxy,cn=etc,dc=stt,dc=local -

HTTP/ipa1.stt.local@STT.LOCAL

ldap/ipa1.stt.local@STT.LOCAL

Check if the DNA range configuration for the deleted master does contain dna 
RemainingValues other than 0. In that case you might want to check DNA 
configuration of other masters to be sure that other master can issue posix 
numbers.

DNA ranges could be also configured using ipa-replica-manage.

Yes, the other servers are there and seem to handle the right stuff

Could  be seen e.g., when browsing LDAP structure in Apache Directory studio as 
Directory Manager. It's 'aci' attribute of entry 
cn=masters,cn=ipa,cn=etc,$SUFFIX

There should be two which contain the deleted replica hostname. One has name 
"Read IPA Masters" the other "Modify IPA Masters".

----
Not sure I understand.

There are entries for the 3 servers in question
Ipa1, ipa3, ipa4 but in cn=masters,cn=ipa,cn=etc,$SUFFIX there isn't anything 
(i.e. attributes) that are called IPA Masters or Modify IPA Masters under any 
of them.

Thanks
