This is a very strange issue. We had enabled Unix AD LDAP integration against our Windows Domain: abc.com.
We had two locations, the following information is how did I install Unix AD LDAP for windows Domain authentication.
** Primary DC (FSMO owner of domain): master.abc.com (located in the europe office): Installed "Identity Management for Unix" in this DC
** two DCs: dc1.abc.com, dc2.abc.com (located in the sydney office)
** some LDAP configuration in Unix.
Everything was working fine, However, few weeks ago, When I tried to manage Unix Attributes tab in the ADUC of two DCs in Sydney office, It is reporting invalid information, and I cannot do anything in the Unix Attributes tab. However, I can configure Unix Attributes tab in master.abc.com, But it doesn't work whatever changes I made.
Thanks for your help.
