Your olcAccess: {1} value does not belong in your back-MDB database. That rule goes in the {-1}frontend,cn=config portion of the database as a global access rule. You probably also want a rule that reads:
to dn.base="cn=subschema" by * read
in the {-1}frontend,cn=config database as well.
So for your back-mdb database, what one would expect is more something like:
olcAccess: {0}to attrs=userPassword,shadowLastChange by self write by anonymous auth by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read olcAccess: {1}to dn.children="ou=ABC Customer,dc=core,dc=hdt,dc=hu" by self write by group.exact="cn=groupabcadmin,ou=ABC Customer,dc=core,dc=hdt,dc=hu" write by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read olcAccess: {2}to * by * read

what does it reveal? This rule comes with the default installation...
You probably also want a rule that reads:
to dn.base="cn=subschema" by * read
the frontend config is this:
dn: olcDatabase={-1}frontend,cn=config objectClass: olcDatabaseConfig objectClass: olcFrontendConfig olcDatabase: {-1}frontend olcAccess: {0}to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth manage by * break olcAccess: {1}to dn.exact="" by * read olcAccess: {2}to dn.base="cn=Subschema" by * read
in the {-1}frontend,cn=config database as well.
So for your back-mdb database, what one would expect is more something like:
olcAccess: {0}to attrs=userPassword,shadowLastChange by self write by anonymous auth by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read olcAccess: {1}to dn.children="ou=ABC Customer,dc=core,dc=hdt,dc=hu" by self write by group.exact="cn=groupabcadmin,ou=ABC Customer,dc=core,dc=hdt,dc=hu" write by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read olcAccess: {2}to * by * read
well, at first look it works - many thanks again.
I'll check it all config tomorrow.

Hi all,

now the rules are:
dn: olcDatabase={1}mdb,cn=config olcAccess: {0}to attrs=userPassword,shadowLastChange by self write by anonymous auth by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read by * none olcAccess: {1}to dn.children="ou=ABC Customer,dc=core,dc=hdt,dc=hu" by self write by group.exact="cn=groupabcadmin,ou=ABC Customer,dc=core,dc=hdt,dc=hu" write by dn="uid=repuser,dc=core,dc=hdt,dc=hu" read olcAccess: {2}to * by * read
and a member of cn=groupabcadmin,ou=ABC Customer,dc=core,dc=hdt,dc=hu can modify any attributes at any users under the ou=ABC Customer, EXCEPT the userPassword - when I want to modify that, I get permission error:
ldap_modify: Insufficient access (50)

How can I combine the attrs and group permissions? Should I list all attributes in rule?
Thanks,
