LDAP configuration ACL on centos 7

I'm trying to set ACL for Manager user by I understand where is my syntax error.

Is it correct to modify the "olcDatabase={2}hdb" file??

My Terminal command:

ldapmodify -a -x -D "cn=Manager,dc=gruppo6,dc=labreti,dc=it" -w root -H ldap:// -f acl.ldif

And this is the error:

ldapmodify: invalid format (line 5) entry: "olcDatabase={2}hdb"

acl.ldif:

dn: olcDatabase={2}hdb
changetype: modify
add: olcAccess
olcAccess:{0} to * by dn="cn=Manager,dc=gruppo6,dc=labreti,dc=it" manage by * break
{1} to attrs=userPassword by dn="cn=Manager,dc=gruppo6,dc=labreti,dc=it" write by self write by anonymous none by users none
{2} to attrs=loginShell by dn="cn=Manager,dc=gruppo6,dc=labreti,dc=it" write by self read by anonymous none by users none to attrs=uid,sn,homeDirectory by self write
{3} to dn.subtree="dc=gruppo6,dc=labreti,dc=it" by * read

olcDatabase={2}hdb.ldif:

There are 2 issues :

  • You are trying to modify olcDatabase={2}hdb using the wrong dn in acl.ldif, this entry should be in the subtree of cn=config. You can grab the target olcDatabase using this command :

    slapcat -n 0 -a olcDatabase=hdb

# Output 
dn: olcDatabase={2}hdb,cn=config
...

  • Since you are modifying an existing entry, you don't need the -a flag (ldapadd) in ldapmodify command : 

    ldapmodify -x -D "cn=Manager,dc=gruppo6,dc=labreti,dc=it" -w root -H ldap:// -f acl.ldif

If your ldap manager precisely cannot modify this config entry due to insufficient permissions (reading from this directive to * by dn="cn=Manager,dc=gruppo6,dc=labreti,dc=it" manage), you can still use external binding (unix user) to perform that kind of operation :

ldapmodify -Y EXTERNAL -H ldapi:/// -f acl.ldif
