Problem: After SAML login umc modules are not useable

Problem

After SAML login umc modules are not useable, as they will not open.

Environment

UCS 5 (maybe also UCS 4.4)
SAML Logon
High count of group membership

Solution

Use direct login (without SAML) or if this is not option reduce the number of group membership
How many are possible depends on system capacity (I/O, network, cpu and as always RAM)

Root Cause

Bug 54032
