ArcGIS Server edit role fails with "Another administrative operation is currently accessing the store"

Question

I just installed a vanilla instance of ArcGIS Server 10.3.1 on Windows 2008. From the manager webapp I opened Security -> Settings, then configured the server to use:

User Store: LDAP
Role Store: LDAP
Authentication Tier:    Web
Authentication Mode:    Web

Then I opened Security -> Roles and clicked the edit icon next to the role I want to use as administrator. I get the expected message:

Role information is being managed externally in your enterprise's LDAP server. As a result, this information cannot be modified in Manager. Only the 'Role Type' attribute, which is managed by ArcGIS Server, can be modified.

I click the radio button to set Role Type to Administrator and click Save. After working on it for 30 seconds or so, this message is displayed:

Another administrative operation is currently accessing the store. Please try again later.

I have tried everything I can think of from trying again later, to a full uninstall/reinstall of ArcGIS server... Any suggestions as to what could be causing this?

--- UPDATE ---

I tried following this process on a brand new Windows 2012 VM. Same problem... The headache continues...

--- UPDATE 2 ---

I uninstalled everything and this time installed 10.4 following the same instructions. Now when I try to set the Role Type, I get a much more informative error:

    Illegal char <|> at index 52: C:\arcgisserver\config-store\/security/roles\global |-| global arcgis administrators.json\

It looks like ArcGIS LDAP integration does not support all valid names. I can't really see a way around this other than:

1. File a report with ESRI
2. Replicate group to another one with a name not including an | character.

ARGH!

--- Update 3 ---

For ESRI, the role name is Global |-| Global ArcGIS Administrators

Answer 1

While this doesn't help my situation, the answer is, ArcGIS Server does not support all the same characters in Role names as LDAP does. Hence, having a role with | in the name, will cause the edit operation to fail with the ever-so-useful error:

Another administrative operation is currently accessing the store. Please try again later.
