kadmin.local -q "add_principal [email protected]"
kinit [email protected]
Option 1:
kadmin.local -q "ktadd -norandkey [email protected]"

kadmin.local -q "xst -norandkey [email protected]"
Test User:
kinit -kt /etc/krb5.keytab user
getent passwd user
id user
login user
Delete User:
ldapdelete -x -D "cn=admin,dc=example,dc=com" 'uid=user,ou=People,dc=example,dc=com' -w admin_pass

Option 1: Possible incorrect password. Did you export the principal with norandkey? By default ktadd exports changes the key to a random one. Can you loging with kinit [email protected]?
Example:
kadmin.local -q "ktadd -norandkey [email protected]"
kinit [email protected]
Do not use, automated in makefile.
