I am attempting to connect to a Microsoft SQL Server database on a corporate network that is limited to Windows Authentication. I have configured Kerberos and Kerberos does successfully issue a ticket and I can verify that the ticket is valid in Ticket Viewer. But when I attempt to connect in Azure Data Studio, and select "Windows Authentication", I am given the message "Connection Failed due to Kerberos Error".
My krb5.conf is located at ~/etc/krb5.conf and I have followed configuration instructions here.
On a Windows machine connected to the network, when I run setspn -L DATABASENAME
I show:
Registered ServicePrincipalNames for CN=DATABASENAME,OU=Servers,OU=Data Center,DC=companyname,DC=com:
MSServerClusterMgmtAPI/DATABASENAME
MSServerClusterMgmtAPI/DATABASENAME.companyname.com
WSMAN/DATABASENAME
WSMAN/DATABASENAME.companyname.com
TERMSRV/DATABASENAME
TERMSRV/DATABASENAME.companyname.com
RestrictedKrbHost/DATABASENAME
HOST/DATABASENAME
RestrictedKrbHost/DATABASENAME.companyname.com
HOST/DATABASENAME.companyname.com
When I run nslookup -type=srv _kerberos._tcp.companyname.com
I show:
Server: UnKnown
Address: xx.x.x.163
Non-authoritative answer:
_kerberos._tcp.companyname.com SRV service location:
priority = 0
weight = 100
port = 88
svr hostname = dcname01.companyname.com
_kerberos._tcp.companyname.com SRV service location:
priority = 0
weight = 100
port = 88
svr hostname = dcname02.companyname.com
_kerberos._tcp.companyname.com SRV service location:
priority = 0
weight = 100
port = 88
svr hostname = dcname03.companyname.com
_kerberos._tcp.companyname.com SRV service location:
priority = 0
weight = 100
port = 88
svr hostname = dcname04.companyname.com
dcname01.comapnyname.com internet address = xx.x.x.47
dcname02.companyname.com internet address = xx.x.x.8
dcname03.companyname.com internet address = xx.xx.x.11
dcname04.companyname.com internet address = xx.xx.x.10
The way I have my krb5.conf file configured is:
[libdefaults]
default_realm = COMPANYNAME.COM
[realms]
COMPANYNAME.COM = {
kdc = dcname01.companyname.com
kdc = dcname02.companyname.com
kdc = dcname03.companyname.com
kdc = dcname04.companyname.com
}
I have tried many different configurations for krb5.conf involving inclusion and omission of different k/v pairs in different formats but nothing I have tried has worked. I have also attempted to reinstall krb5 via homebrew.
I am using an Intel Mac on macOS 12.3.1.
What would be causing Azure Data Studio to not acknowledge my Kerberos Ticket?
