$krb5asrep$svc-alfresco@htb.local:... Bingo. No pre-auth required. You copy the hash to a file and feed it to john : forest hackthebox walkthrough
ldapsearch -H ldap://10.10.10.161 -x -D "CN=svc-alfresco,CN=Users,DC=htb,DC=local" -w s3rvice -b "DC=htb,DC=local" "(memberOf=CN=Remote Management Users,CN=Users,DC=htb,DC=local)" No. But you find another group: Service Accounts .
