##### ISSUE TYPE

* Bug Report

##### COMPONENT NAME

~~~
ldap
~~~

##### CLOUDSTACK VERSION
~~~
4.19
~~~

##### CONFIGURATION

Advanced Networking, Domain tree with multiple subdomains

##### OS / ENVIRONMENT

RHEL 9.3
VMware 8.0c (8.0.0.3)
LDAP 389 Directory Server

##### SUMMARY

If I create ldap account in domain with ldapCreateAccount, then link this account to ldap group with linkAccountToLdap, I'm not able to create another account in the same domain. I got error:
CloudStack error: HTTP 534 response from CloudStack
{
"createaccountresponse": {
"cserrorcode": 9999,
"errorcode": 534,
"errortext": "No LDAP user exists with the username of test_user",
"uuidList": []
}
}

If I create multiple accounts with ldapCreateAccount first, then I'm able to link all these accounts to ldap groups with linkAccountToLdap. But again, not able to create any other new ldap accounts

##### STEPS TO REPRODUCE

~~~
cs --post ldapCreateAccount username=test_admin account='Test admins' accounttype=2 domainid=6xxxxxx0e-d170-48ea-a9bf-90fexxxxx122
cs --post linkAccountToLdap account='Test Admins' accounttype=2 domainid=6xxxxxx0e-d170-48ea-a9bf-90fexxxxx122 ldapdomain='cn=test admins,cn=test,ou=groups,dc=my,dc=domain,dc=com' type=GROUP
cs --post ldapCreateAccount username=test_users account='Test users' accounttype=0 domainid=6xxxxxx0e-d170-48ea-a9bf-90fexxxxx122
~~~

##### EXPECTED RESULTS

~~~
Create another account in ldap and link it to another ldap group
~~~

##### ACTUAL RESULTS

~~~
CloudStack error: HTTP 534 response from CloudStack
{
"createaccountresponse": {
"cserrorcode": 9999,
"errorcode": 534,
"errortext": "No LDAP user exists with the username of test_user",
"uuidList": []
}
}

在所描述的 CloudStack 4.19 LDAP 設定中，使用 ldapCreateAccount，接著使用 linkAccountToLdap 重現此問題，然後檢查 LDAP 帳戶建立與群組連結的進入點。完成的標準是：可以在相同網域中建立第二個帳戶，並將其連結至另一個 LDAP 群組，而不出現 HTTP 534 錯誤；pull request #13945 已經開啟。
