LDAP Authentication Failure

[maryamelahi]

hi so it is an emergency  and odd one .here is my problem : all computers witch can logon to all computers under this setting: "active directory account Tab on log on to" can authenticate with ldap server and nothing's wrong.but all those computer which just can log on to their computer during the last setting( "on active directory account Tab on log on to") authentication failure message just show up. and here is the  LDAP Setting on Fortigate:

config user ldap edit "LDAP-sanjeshdc1" set server "192.168.*.*" set cnid "sAMAccountName" set dn "dc=******,dc=net" set type regular set username "user with privilege " set password:...

>ensure the  Base dn search  is correct and the account > run cli-cmd diag test authserver ldap

 > if that fails with a timeou, validdate LDAP or LDAPs us cli-cmd   diag sniffer packet any "port 636 or 389"
