LDAP Authentication for LTM administration

Was it bad DNS settings?

This was a loooong time ago, but it appears I've documented several reasons for login delays - I've encountered this situation more than once. 1. Bind account locked out. Our AD does not allow anonymous queries, so we must bind to AD with a valid account in order to validate anyone else's credentials. We created an application ID for this specific purpose, and if it's locked out, no one's AD credentials can be validated which results in a delay (and an unsuccessful login). 2. DNS Search Domain in /etc/resolv.conf At some point, we had a **search localhost.com** directive in our /etc/resolv.conf. Since this was not a valid DNS domain in our environment, this entry caused a delay in DNS resolution. Commenting out this entry resolved this situation. 3. Invalid/impaired/inaccessible DNS server - this will also cause login delays. If the DNS has been changed, I have also found that I needed to restart the httpd service - this does not have any impact on LTM traffic processing. 4. Restart the httpd process - I've had to restart this process after updating DNS settings. HTH
