Setup Config Admin

First of all, let’s search for the right entry in our ldap-tree:

dr@tardis:# ldapsearch -LLL -Y EXTERNAL -H ldapi:/// -b cn=config

In this output we can find our cn=admin,cn=config

dn: olcDatabase={0}config,cn=config
objectClass: olcDatabaseConfig
olcDatabase: {0}config
olcAccess: {0}to * by dn.exact=gidNumber=0+uidNumber=0,cn=peercred,cn=external
 ,cn=auth manage by * break
 olcRootDN: cn=admin,cn=config

Now lets encode our password using the following command:

slappasswd -h {SHA}

So we can create our modification.ldif now:

dn: olcDatabase={0}config,cn=config
changetype: modify
add: olcRootPW
olcRootPW: {SSHA}

And enable it with the following command

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