Can authenticate to Open Directory, but can’t alter data [RESOLVED]

Hi,

I am having a really weird issue: I can connect to my open directory (using diramin), but for a reason I can’t figure out, anything related to altering the data (creating user, modifying user, etc.) are impossible (icons greyed).

I’m not sure, but I think this issue came after an update to 10.4.3.
Anyone having this problem too?
Any idea on how I should resolve this problem?

Update: in the console log, I do have the following lines:

GSSAPI Error: Miscellaneous failure (Server not found in Kerberos database)
DSLDAPv3PlugIn: Required Policies not Supported: Packet Encryption.  LDAP Connection for Node 127.0.0.1 denied.

Update 2: I found out that I had a bad settings: in Settings->Policy->Binding, I had checked “Encrypt all packets.” When I unchecked it it worked again.

Thanks in advance.

Regards,
Jerome.
