+# Change Distinguished Name (DN) in OpenLDAP Docker
+
+This document provides a step-by-step guide on how to rename the Distinguished Name (DN) from `cn=administrator,dc=flock,dc=town` to `cn=administrator,dc=cymais,dc=cloud` in an **OpenLDAP Docker** environment.
+
+**Reference:** [Conversation Link](https://chatgpt.com/share/67d9a2f7-4e04-800f-9a0f-1673194f276c)
+
+---
+
+## 1. Export the Current Entry
+
+Connect to the OpenLDAP container and export the current entry:
+
+```sh
+docker exec -it ldap sh -c 'ldapsearch -x -D "$LDAP_ADMIN_DN" -w "$LDAP_ADMIN_PASSWORD" -b "$LDAP_ROOT"' > all_entries.ldif
+```
+
+If your ***LDAP_ADMIN_DN*** and ***LDAP_ROOT***  are not accured pass them via ``--env``.
+
+---
+
+## 2. Modify the LDIF File
+
+Open `all_entries.ldif` and update the DN (`dn:` line) and `dc` attributes.
+
+- Open the file in an editor (`nano`, `vim`, `sed`).
+- Replace **all occurrences** of `dc=flock,dc=town` with `dc=cymais,dc=cloud`.
+
+**Using `sed` to modify automatically:**
+```sh
+sed -i 's/dc=flock,dc=town/dc=cymais,dc=cloud/g' all_entries.ldif
+```
+
+**Before:**
+```ldif
+dn: cn=administrator,dc=flock,dc=town
+cn: administrator
+objectClass: organizationalRole
+objectClass: simpleSecurityObject
+userPassword: {SSHA}...
+```
+
+**After:**
+```ldif
+dn: cn=administrator,dc=cymais,dc=cloud
+cn: administrator
+objectClass: organizationalRole
+objectClass: simpleSecurityObject
+userPassword: {SSHA}...
+```
+
+---
+
+## 3. Delete the Old Entry
+
+### Generate a Recursive Delete LDIF
+We need an **LDIF file that deletes all objects** under `dc=flock,dc=town`.
+
+Instead of manually writing an LDIF file, you can use `ldapsearch` and `awk` to generate it dynamically:
+
+```sh
+docker exec -it ldap sh -c 'ldapsearch -x -D "cn=administrator,dc=flock,dc=town" -w "$LDAP_ADMIN_PASSWORD" -b "dc=flock,dc=town" dn' | awk "/^dn:/ {print \$2}" | tac > delete_all_dns.txt
+```
+
+This creates an **ordered delete list**, starting with child objects before deleting `dc=flock,dc=town`.
+
+---
+
+#### Apply the Recursive Delete
+Now apply the generated `delete_all.ldif` to delete all entries **recursively**:
+
+```sh
+docker exec -i ldap sh -c '
+while read dn; do
+  ldapdelete -x -D "cn=administrator,dc=flock,dc=town" -w "$LDAP_ADMIN_PASSWORD" "$dn"
+done' < delete_all_dns.txt
+```
+
+---
+
+#### Verify That Everything Is Deleted
+After running the delete command, verify that `dc=flock,dc=town` is empty:
+
+```sh
+docker exec -it ldap sh -c 'ldapsearch -x -D "cn=administrator,dc=flock,dc=town" -w "$LDAP_ADMIN_PASSWORD" -b "dc=flock,dc=town"'
+```
+- ✅ If **no results** are returned, the domain has been deleted successfully.
+- ❌ If results still exist, some entries were not removed.
+
+
+#### Create new_database.ldif
+
+docker exec -i ldap ldapadd -Y EXTERNAL -H ldapi:/// -f /dev/stdin < new_database.ldif
+
+## 4. Add the New Entry
+
+Now, upload the modified `all_entries.ldif`:
+
+```sh
+cat all_entries.ldif | docker exec -i ldap sh -c 'ldapadd -x -D "cn=admin,dc=cymais,dc=cloud" -w "$LDAP_ADMIN_PASSWORD"'
+```
+
+---
+
+## 5. Update Root DN Configuration
+
+If `cn=administrator` is used as `rootdn`, update the OpenLDAP configuration file (`slapd.conf` or `olcDatabase={1}mdb.ldif` under `cn=config`).
+
+Find:
+```ldif
+olcRootDN: cn=administrator,dc=flock,dc=town
+```
+Replace with:
+```ldif
+olcRootDN: cn=administrator,dc=cymais,dc=cloud
+```
+
+Save the change and apply it:
+
+```sh
+docker exec -it ldap ldapmodify -Y EXTERNAL -H ldapi:/// -f config_update.ldif
+```
+
+---
+
+## 6. Restart OpenLDAP
+
+Restart the OpenLDAP container if necessary:
+
+```sh
+docker restart ldap
+```
+
+Now, `cn=administrator,dc=cymais,dc=cloud` should be active as the new administrator account.
