When ipa-getkeytab is used to fetch trusted domain object credentials, the fetched entry has always kvno 1. ipa-getkeytab always adds a key to keytab which means older key versions will be in the SSSD keytab and will confuse libkrb5 ccache initialization code as all kvno values are equal to 1. Wrong key is picked up then and kinit fails. To solve this problem, always remove existing /var/lib/sss/keytabs/forest.keytab before retrieving a new one. To make sure script's input cannot be used to define what should be removed (by passing a relative path), make sure we retrieve trusted forest name from LDAP. If it is not possible to retrieve, the script will issue an exception and quit. If abrtd is running, this will be recorded as a 'crash' and an attempt to use script by malicious user would be recorded as well in the abrtd journal. Additionally, as com.redhat.idm.trust-fetch-domains will create ID ranges for the domains of the trusted forest if they don't exist, it needs permissions to do so. The permission should be granted only to cifs/ipa.master@IPA.REALM services which means they must have krbprincipalname=cifs/*@IPA.REALM,cn=services,... DN and be members of cn=adtrust agents,cn=sysaccounts,... group.
