OK all, really going nuts here. wbinfo -u/-g works, pulls up the W2k users/groups. Net ads join works just fine. Created the krb5.keytab file on the w2k machine and kutil copy this to /etc/krb5.keytab. kinit administrator works fine. However, all net groupmap commands fail. Here's an example: fskkweb# net groupmap add unixgroup=admin ntgroup="Domain Admins" No rid or sid specified, choosing algorithmic mapping [2004/09/29 08:42:46, 0] lib/smbldap.c:smbldap_open_connection(623) Failed to issue the StartTLS instruction: Decoding error [2004/09/29 08:42:47, 0] passdb/pdb_ldap.c:ldapsam_search_one_group(1873) ldapsam_search_one_group: Problem during the LDAP search: LDAP error: 000020D6: SvcErr: DSID-03100684, problem 5012 (DIR_ERROR), data 0 (Operations error) <Snip-error burps out for quite a number of lines> [2004/09/29 08:42:47, 0] passdb/pdb_ldap.c:ldapsam_search_one_group(1873) ldapsam_search_one_group: Problem during the LDAP search: LDAP error: 000020D6: SvcErr: DSID-03100684, problem 5012 (DIR_ERROR), data 0 (Operations error) adding entry for group Domain Admins failed! fskkweb# I'm assuming there is some problem with openldap client. ldapsearch burps out this: fskkweb# ldapsearch -v -D CN=Administrator,CN=Users,DC=fsklaw,DC=net ldap_initialize( <DEFAULT> ) ldap_bind: Invalid credentials (49) additional info: 80090308: LdapErr: DSID-0C09030B, comment: AcceptSecurityContext error, data 52e, v893 Any body have any clues...I would love to get this working.
