vytvorim db krb5_newrealm, upravim kadm5.acl, kde vlozim */admin@local.mojedomena *, a ted kdyz chci spustit kadmin -p admin/admin, tak to zahlasi: kadmin: Missing parameters in krb5.conf required for kadmin client while initializing kadmin interface. Ano, rozuim tomu, ze mi tam neco chybi,ale co?
1.) Az po jaky bod se musim dostat tak, abych mohl pokracovat v integrovani samby v druhem navodu? Tam pisou, ze kerberos musi byt nakonfigurovan, tak kdy poznam, ze je nakonfigurovan? Az pridam uzivatele?
2.) Nejdrive musim vytvorit uzivatele na linux pc, potom v AD, a heslo uz si bude overovat pres AD?
3.) Kdyz chci propojit infrastrukturu linux-windows, udelal bych LDAP synchronizaci s AD, a u ldapu by musel bezet jeste kerberos?
4.) Nikdy nedocilim toho, ze AD mi bude ridit i vytvaret ucty i na linuxech?
Cetl jsem toho dost, a ted se to snazim vstrebat, diky za pomoc

Kde LOCAL.MOJEDOMENA je název domény v AD
a 10.0.0.5 IP adresa AD serveru,
ano?Díky

password server = ad_server_1.local.mojedomena _ad_server_2.local.mojedomenanebo

[domain_realm] local.mojedomena = LOCAL.MOJEDOMENATo jsem pochopil asi že je to jen asociace.
libnss_winbind.so libnss_winbind.so.2 -> libnss_winbind.so libnss_wins.so libnss_wins.so.2 -> libnss_wins.soAle co když jsem nekompiloval, ale instalovat z balíčku? a další věc je PAM, kam stím?

Takže jsem vrátil z5 zálohu a nevím co stím...
