LDAP Integration Status changes by itself in Unity

[dgragg002]

Unity 12.5.1

Have several users that were built under LDAP and had the setting of Intergrate with LDAP Directory. 

However, intermittently , we get a user that it will switch to "Do Not" intergrate. 

They will get a contact Administrator and when we switch it back it works fine. 

Any ideas? 

Thanks
