Binding from CLI:
The functionality of Directory Utility and the Directory payload is also accessible from the command-line interface with the dsconfigad command. For example, the following command can be used to join a system to Active Directory:
dsconfigad -preferred ads01.example.com -a COMPUTERNAME –domain example.com -u administrator -p "password"
After you’ve bound a system to the domain, you can use dsconfigad to set the administrative options in Directory Utility:
dsconfigad -alldomains enable -groups domain admins@example.com, enterprise admins@example.com
Note: Using dsconfigad in a script requires using clear text for the password. Configuration profiles are preferred.

Increased logging:
odutil set log debug
Stored in: /var/log/opendirectoryd.log
(persists across restarts)
Standard logging:
odutil set log default
Disable packet encryption while troubleshooting:
dsconfigad -packetencrypt disable
dsconfigad -packetencrypt allow
TCP Dump Example:
tcpdump –K -i en0 -s 0 -w capture.pcap port 88 or port 464 or port 53 or port 389 or port 3268
DNS Troubleshooting:
dig -t SRV _ldap._tcp.example.com
telnet dc01.example.com 88
TCP 88 - Kerberos
TCP 389 - LDAP
TCP/UDP 464 - Kerberos password changes
TCP 3268 - Global Catalog
